Berni I really hope he sent you another laser!

OH, he love you long time! :eg::beer:

The sad part is that he is quite likely wondering why people here are so evil and will not buy his lasers.

1. Quality support.
2. Product quality.
3. Customer service.

They fail on all 3.

Yes I am aware of that.
My point is that he seems incapable of seeing it.
He just kept going in the same track, getting more and more agitated.

Well, his problem there are enough good companies out there.

Wait,

So Berni opened the laser to modify the driver? Did the laser die before or after that?

I guess Livi did say to modify the driver to get 1W of power though...

Its just typical delusion of self grandeur. He is not wrong, everyone else is. A humble person will always succeed, because there is always room for improvement.

I understand that, but was the laser dismantled before or after it broke?

I haven't been around as much lately and missed everything that's been going on. If the laser was dismantled before it broke I don't see how someone could expect a warranty to cover the damages.

Livylasers / whoever this clown is is still an incredible egomaniac who sells underpowered lasers, but that doesn't mean that you can try to modify something under warranty then expect free repair when it doesn't work out.

I need to read more about what happened...

Berni never made any changes to the driver, he just figured out what to do to it to get the 1w instead of 740mw. He was going to have the parts sent to me and then I would send them to him, since the company he was getting the parts from was going to charge $35 to send a $2 part to Israel.

He told people to open the laser, and increase the power themselves. He probably should not told people that, because it sounds like he was backing up people screwing with their lasers.

Yeah, I remember that.

Livilaser is still cheap crap, especially with the owner (only employee ) being a pompous ass.

He explained that anyone unhappy with the power could just open it and turn the potmeter.
When someone tried and pointed out that there were no potmeter, the story changed to the 800mW being a feature to increase duty cycle.

For all I know the driver is a modified flashlight driver with spikes that would be ok for a LED, but kill a LD pretty quickly. That would at least be consistent with the rest of the company impression.

You know for $170 I got my LVYI laser, decent safety glasses, battery charger and shipping, I don't have an lpm but after Jerry tested his and a couple of others I figure mine is around 740mw, and got it in about 15 days. That was better than WL when I ordered my arctic waited for 2 months and wound up canceling my order. I have not had any problems with it, it burns good, and the focus is really smooth, I can't complain.

But after LVYI came on he forum and started ranting, I won't do any more business with them. What he did was just total bullshit.

Jeff

I agree, he banning him was the right decision. It's obvious that the laser did not meet the advertised specifications. On top of the customer service issues, I see no reason to purchase from him unless the quality could be guaranteed. So far, they've missed the mark.

Also, he shouldn't assume that no one on the forum can understand what he's saying just because it's in chinese. Yelling at us in another language seems a little immature. Here's a translation of his last few messages. I'm glad he's banned.

What do you want to say, piece of trash, next time buy elsewhere, trash, it's cheap and you're still hesitant, if you're smart you'd take advantage of this.

Hi Pontiac,

It's the 3 times I need to justify myself !
I give you the story board:
09 September, I order the laser, after few days I got mail from lvyvi that battery will not be shipped ! :yabbmad:
I make order 2x3.6 batterys on Ebay and have about 3 weeks to wait for hong kong shipping.
15 september laser review: 742mW for laserbee and 600mW for yobresal.
wait and see....
At least I got my laser the 20 september but I haven't batterys !:scowl:
I need to test it ! so ,I take it to my Lab at work (motorola communication) and powered the laser with my H.P. stabilized power supply. Under 7.4V or 8.4V laser work make a big blue cercle and a little too take 700mA max.
I work (and like) electronic , I want to take a look at the driver
I verify my ESD bracelet and take off the driver from the laser tub and see that is an PT4115 based driver. I take a picture for forum member and reassemble the laser. put into his case and waiting for the battery.
I begin to seach on Internet information about this pt4115 based driver.
And posted to forum member all informations that i find on PT4115.
look my other post...
I receive my 2 battery only few days ago. I am happy, I can't test his power but i can test burning .....I put black tape less than meter in front of the laser power on and.....nothing. I take my other 200mw red from DX and test burning...a lot of smoke it's OK.
I am thinking that my blue laser is far away from 1W. And thinking seriously to find parts to modifie the driver.
Meantime I am playing with my beautiful laser make demos to my friends ...
Then..26 september my laser begin with flashs !! I power off , verifie batterys Ok, and power on again ...get only weak light like standart led. !
I send my first mail to lvyilaser to get an address for return.
I am supprised, he ask $25 + double shipping for an laser under garanty.
I am not ready for that, if problem is only the driver , I can order Led driver to DX with exactly the same parts and repair my lvyilaser driver.
So I need to know where is the problem: 445 led or driver.
I buy parts to built a test load , parts are easy to find in town.
I take laser to my work .....connect ESD to my bracelet / solders Iron on
I deconnect the led to connect the load to the Driver.
Power the driver under 8V , Test is OK driver give me 4.5V/800mA( and can also 5.5V/800mA.) I am now 100% sure that the led is dead.
I reassemble the laser, power on, no change, weak !
I send my second mail to lvyilaser, to inform that 445 led is dead.
I am shocked, now he want $50 + double shipping (+ $15 that I need to paid again for custom fee).
I was decided to stop communication with lvyilaser and co.
And ready to buy A140 led to kiyoukan for 40.50 shipped world wide.

I am really disappointed with all this story, I NEVER modified the driver, and only wanted to help member to find a solution to get really 1W laser.
If lvyilaser send me a new laser, I will return the bad one with tracking # I hope that I will not read another mail (sabotage/untruthful/insulte....) about this lamentable story.
Bernard
