Priceangels: cool gadgets in the right price,worldwide free shipping



Hello, all friends who trust us all the time,all members who concern about us all the period,　thanks all.


This period has been really a hald time for me, I sacrifice much because of the underspecs of my products, I have to do full refund and full shipping fee refund again and again, even it is only a $10 30mw green pointer keychain that turns out to be only 15mw. It's really not so easy for my company. But as I said, john will always be reliable john, priceangels will alway be reliable priceangels.


I have told all members to cancel their order in the thread sorry to all if them are trying to get a full output one. some of the kind friends don't cancel their orders, but ask for full refund and full shipping refund after receiving it. And I agreed.


It's really not so easy for me and my bussiness.


But now, the change has come: the LPM from lasersbee arrived!

We will test our lasers, maybe not all of them, but will choose 5 samples for each kind of laser. Then give you a detailed data as you wish.


From this moment, we will try our best to test them as soon as possible, and the results will be available in our website. Thanks for all you support all the time!If you have some more advices to my company or some suggestion in the usage of LM, please feel free to tell me, I will listen to you always.


thanks all, god bless you!


reliable john.

That's great news!

yes, great news for me!
But we may have some trouble in the usage of the LPM. we have no professional laser user. Wish it is easy.

Lasersbee's aren't that great of an lpm, especially for a professional business.

It should not be hard. If anything doesn't work, just take and post lots of pictures to let people see what you're doing. Everyone here will be glad to help, especially if it means helping a cheap source of known power lasers. I'm very interested to see your results, and big props on trying to do this right.

Then, how about your suggestioin, jay? As far as I know lasersbee LPM has been proved to be one of the best in LPF. And I choose the one which all members suggest me to get.

Hi John,
Thanks for the PM to clear everything up for me.
I do have some advice about testing now that you have a meter.
My advice is that each laser is tested and output power recorded.
My reasons are several.
1. It does not take much time and increases quality control.

2. Testing 5 or even 10 pcs of each model may give a customer a general idea of the output range of a certain model, but it will really apply in general to that lot. I've found that each one really needs testing and changes can occur at anytime, it could be the particular assembly line, person doing the assembly or alignment not to mention qualtiy of the crystals and other components which can change on dime.
I've been there and seen it happen before my eyes, luckily each of my lasers is tested before sending them to a customer. There have been time that entire shipments were rejected and sent back.

3. Testing each one, helps to ensure that the customer will be happy with the product they order and the laser works correctly the 1st time.

4. Testing each one ensures that no under powered lasers get shipped to customer and then need to be returned for replacement.

5. When a customer gets a bad laser that needs to be sent back, it costs you time and money which will destroy any amount you made on the order as well as waste the customer's time and money if they have to pay return shipping and upsets them as they are now without their laser.

Since you have invested in this laser meter, use it. Use it on every laser and it will save you alot of time & money in the long run and reduce the return rate to almost zero.

Good luck and enjoy your new meter.

ps, having the meter will also allow you to keep your suppliers in line, so they will stop cheating you on the promised output power of their products.

Man this is SWEET. I really aim glad you came a joined this forum. The Angel in PriceAngels"" Is You.!!

Thanks again cant wait till you get settled in.

Lasersbee is a great LPM.
Does your model have data logging?


You just power it up, and shine the laser at it.....

Data logging you just plug it into the computer and open the software, click record and then measure the laser.

Honestly? I'd get a kenometer. He's out of thermopyles though but lasersbee has them. I would get a real thermopyle from lasersbee since he bought them all out and use it with the Kenometer you can pickup from Kenom.

Has a nice program made by MarioMaster too. Beautiful design.

The thermopile that came with your lasersbee is not a real thermopile. It's a substitute called a wafer thermopile I think.

John, it's a heck of a lot better than not having a meter.
It's not a professional meter with NIST calibration, but it gets you in the ballpark.
A professional meter costs 2-3k and it costs me well over $200 each year to just get mine calibrated and I suppose that calibration cost each year adds a few cents to the price of every laser we sell.

Imho, laserbee LPM is a good instrument, you only need to use it in the right way, cause thermopiles discs and TEC sensors have different phisical characteristics and response times .....

As for any other TEC sensor, you need to:

First: do not hold the heatsink / sensor with your hand, nor place it on anything hot or cold, that can change its temperature (a normal wood table, or a wood plate, it's ok), and don't use it where you have air currents (also blowing on it can change the reading, as you can easily see, if you zero it, then blow on the sensor).

Second: left it thermally stabilize, if you change the place where you made the reading, or if you have hold the heatsink in hand ..... no problems if you use it in the same place all the times, but if you pass form a cold place to a hot one, or vice-versa, you need to wait some minutes, til the heatsink took the same temperature of the place.

Third, after you have zeroed it, place the laser on something stable, that keep it pointed on the sensor area, more centrally possible, at least 20 cm away from the sensor (from 20 to 40 cm is ok), turn the laser on, and keep it pointed on the sensor at least 10 seconds (usually, for read the correct amount of power, TECs requires from 10 to 15 seconds).

And always remember, if the laser is "focusable", ALWAYS check first that the beam is NOT focused in a burning point, before point it on the sensor ..... cause if you point a burning beam on the sensor, you can easily damage the black coating of the sensor, making it imprecise ..... if the laser is focusable, the better thing is always enlarge the beam to 4 or 5 mm diameter, before measure it.

Great John!

According the "30mW keychain" which was mixed up with my 30mW Camouflage star pointer it was worse that it died within 5minutes (2minutes after the I took the vids I send you). The big issue wasn´t the fact that I got the wrong + underspec item, it was more that there was a fail in Quality Control.

But lookin into the future, I´m sure your Laserpowermeter is going to help you and your company according this issue!

Mistakes happen... but I´m sure I´m going to order from PA again in some weeks

As a businessman, I know one can't satisfy everyone's needs. Neither will priceangels or lasersbee LPM can. I believe lasersbee lpm are one of the best in LPF, I like it very much, it's pretty goodl! thanks for all your advice.



Sorry ,I will give you full refund to the wrong product, and half refund to the underspecs products. Have sent you a PM, have you received it ?

This seems hardly constructive criticism. Hes the only bargain laser seller I have heard of to even offer any sort of power testing. Even if its off by 20mw the readings will still be closer than anyone else's on the higher power lasers 150-200+mw. I give the guy props for actually caring that the lasers are under power and I am AMAZED he is willing to test them and post the actual output. If you think that most of these chinese bargain laser sellers actually think their $80 lasers put out 200mw of green you are quite foolish. They just dont care because the average buyer has no idea what mw even means they just know the more it says the better.

Testing every single laser is ridiculous to ask. These arnt high end lab quality lasers, they are chinese bargain lasers for people on a budget. Is he supposed to hire a staff just to test all the lasers? Lets not forget that he doesnt just sell lasers, they are only a small portion of his business. Not to mention I would bet they are drop shipped to keep the prices down so testing of each laser would be impossible. Finally the most obvious problem of all would be how to sell individually tested lasers in his online store. Is he supposed to upload the specs of every single laser within every laser type and price each one based on performance? Then when someone orders one he has to go dig out that specific laser out of the hundreds he would have to keep organized and in physical stock. Thats just not going to happen unless he quadruples his prices. It sounds like a great idea to the buyer because everyone wants absolute certainty of quality and performance but not pay for it.

Im not trying to be harsh on people but John is already bending over backwards trying to satisfy people here and I think its important for us the make realistic suggestions and to appreciate what he is willing to do.

John, I think you are doing exactly what you should. My suggestion would be as follows.

Test 5 lasers of each type

post the manufacturer rated output (so people can see why other sellers outputs are higher)

Post the range and average of your tests

Explain that other sellers only list manufacturer rater output that is inaccurate.

In my opinion you wouldnt even need to do this for all of your lasers just the more popular higher mw rated ones. If someone is buying a 5mw pointer I dont think it really matters if its 3mw or 15mw...maybe thats just my opinion. Of course testing every type of laser cant hurt.

The important thing in my mind is to post the true range and average AND to explain that other sellers ratings are inaccurate! Since all these site have such similar products I think this could make yours really stand out because you show true output.

Your doing a great job John keep it up!

It not hard to do, it's easy with pen pointers and only takes 20-30 seconds time or so each one (of course high end portable lasers do take time).
It's also the only way to show the true output.
If John's a drop shipper, then a meter will be of little use to him unless it's just to verify low output on returned lasers.
A sample of 5, 10 or even 15 units will be of little value statistically unless the reading he gets are all within small range, even then with so many variables like I mentioned in my post above, it would only apply for perhaps that days run of laser on that particular assy. line and assembler.
Using a meter to just sample a small lot every once in awhile will be little more than useless. I've been in the business for almost 6 years now and I'm speaking from experience here.
He doesn't need to put up a webpage listing each individual laser and it's output. All that needs to be done is that each is tested and the power level recorded and included with the laser, as long as a 50mw laser outputs 50mw or more, the buyer won't care and they will know exactly what the output power is.
I'll tell you one thing, it takes alot less time to just test them beforehand than all of the paperwork, time and money to arrange a product return, then test that returned laser and ship a new one that has been tested.
Best just to do it as early in the enitre process as possible or it costs a bundle in time, money and reputation.

Any average power data is infinity more valuable than no power data...statistically speaking

The testing of each laser just will not happen. If turn out wrong ill be the first to put my foot in my mouth.

Without testing each laser before shipped I doubt I would purchase from them. IMO its the only reason for a seller to make use of an LPM.

Insert foot in mouth then.
I test each of the lasers we ship (Optotronics), even the 5mw ones.
I believe other manufacturers like Nova, laserglow and others do as well.
It's not rocket science and it's the only way to ensure the customer gets the power they ordered or if the damn laser really even works and isn't DOA.

If 5 out of 5 "200mw" lasers test 50mw or below...how is that not useful information?

My foot is staying comfortably planted on the floor.

Lets compare

Optotronics Product Details

vs

Focusable 200mW Green Laser Pointer with Safety Key Lock (1*18650 Battery Included) $29.28 Free Shipping

Your 200mw green laser is $569.00 and his is $29.99 shipped

Yeah if you can afford to test every single laser he should be able to too. (where is the emoticon thats bashing its own head in with a hammer?)

Good apples to Lamborghinis comparison

Obviously your lasers are quite a bit nice but my point is that you are making a heck of a lot more money per sale and alot lower volume of sales. Of course you can test each one.

Very Nice John!

This sounds great, to be honest. Laserbee's LPMs all come calibrated and should be at least fairly accurate. At the low power level of the lasers sold on priceangels (I don't expect any can actually exceed 500mW, not sure if they can even reach that), Laserbee's LPM should give a reading with a much lower error than 10-20mW (neglecting environmental conditions), and that is wonderful for a large, Chinese reseller/drop-shipper.

I couldn't be more impressed!

The only advice I would venture to give is that, while testing lasers from batches is good, you should allow customers to request a power reading on the specific laser that is being sent to them. This way, you still have a semi-accurate estimate of the power of your lasers in general, from the 5-10 lasers you test from each batch, AND if the customer is picky enough to want their specific laser tested, you can perform this for them as well. This should appease all parties without taking too much effort like testing every laser would (though it is still the best option for supreme customer service).

Why do these threads always turn into pissing matches?

John testing lasers does not take that much time after you have your LPM set up properly. Like Boot said, 30 seconds or so for each laser. It has been said many times, people dont mind paying a little extra for an onspec laser. Unfortunately this wont work with drop shipping. You'll have to have the lasers go through your company. Its hard to say what you should do. Because lasers vary widely in power, taking 5 or 10 and measuring them will not be a good way to judge the batch. And what if they are all majorly undersprec? Do you return them to the supplier, or sell them cheaper, losing money in the process.

If it was me I'd get all lasers to come to my company. Group them in batches. All green pens in one pile, all green style 1 in another, then style 2, ect. Measure every one in the first batch, and price accordingly. Then measure style 1, ect. For the underspec lasers you can keep the price you have now. For that are onspec charge a little more. For ones that are overspec charge a little more than the onspec.

Also you should not be paying shipping in both direction for returns. Thats bad business. You have openly said many times on this forum that the lasers are underspec, and to hold off buying them till you can set up testing. If people ignore this, its their fault, not yours.

My point is just that you cannot test every single laser and sell at these prices and still expect to make money enough money to make it worth your while. The whole reason these lasers are cheap is because they skip all the expensive stuff like nice parts, high quality control, testing, truthful power ratings etc.

There is a reason these lasers are some much cheaper and that reason is being ignored by alot of people. Testing a few lasers to get a more accurate reading doesnt cost much (but does cost something keep in mind because they can no longer be drop shipped!) that is why its a feasible answer.

Either that or he will have to move to only high quality lasers or only testing the high quality ones so that he can make more $$ per unit just like every other seller who is able to test each laser.

This is a basic concept that all products follow. The quality control at Ferrari is different then at Kia, just like rolex and timex, just like surefire and ultrafire, etc etc etc

The fact that we may be able to get some extra quality control for only slightly increased prices is what I am excited about.

We get your point. Can you stop shoving it down everyone's throat now?
