Dislikes
Not much so far, The only thing I find funny is that the LED indicator is actually brighter than the laser dot it self at times (from a range view). This can be used as a blue flashlight alone...I guess it warns others far away, that hey...Your laser is on! The spring on the charger was a tad sideways...But that's really nothing at all.

As my first power laser, I love it. I cant feel anything that seems to be cheap quality. Everything is made out of metal, even the shutter lens on the aperture. I feel its durable, the threads seem deep so they will last long, and they do put some type of grease on them to pro-long the life.

Focusing
You can focus this laser, to a needle point at close range. The focus style is infinity to close range. It's not like my Bluray DIY laser, where you can shine it 50ft away, and get a LargeDot------FineDot-----LargeDot. In all, The focusing is good and precise.

More about the laser
To start, I emailed the company a few questions.
1) Is this laser protected against reverse polarity? Yes
2) What kind of charger? Smart charger - Stops charging when battery is full.

I was also told it can run fine with a power source of 5v and below, of course. So the laser has a keylock, located at the tailcap, with a simple on off setting (no high med off). I have not yet got to do burning, Will eventually, But I will say the beam is my favorite part. In my room I had the sun blasting in, and my lights on. I was still able to see the beam easily, maybe about the brightness of my 10mw's beam at night, if not even a tad more. At night in a dark room (no smoke of course) the beam is indeed solid, defined, and bright.

The battery they give you is a unprotected Ultrafire. So you have to watch voltage drop, and as stated before, the charger stops automatically. I think out of my few lasers, This is by far my favorite. I received the laser in about a week (China to USA Michigan) And got the battery and keys 2 days later. I have no method to test the true power output of this laser. But in all, I plan to buy my next laser, 200+mW red, from rayfoss, and I would recommend this product to a friend. I beleive it's a good built laser, and again...I cant notice anything that feels cheap. The spring in the laser has a rubber looking material around it, to keep dust / random debris from getting to the circuit.
The package

Laser retail box

What I got in package Day 1

Keys

Unprotected Ultrafire

Aperture

Label / Button / Indicator

Metal threads of course!

Key unit

Key unit other side

Charger

Lighting (bad example)


In reality, i can shine the blue indicator light 50ft away and see decently :p

Questions? Please ask!

Laser beam images / Burn videos will be posted later this week.

I really dont see why people need a "calculator" for measuring divergence. Just measure the diameter at the aperature(Di). Then measure the diameter and any given distance. Diameter(Df) distance(m) then all you have to do is (Df-Di)/m. All you have to do is subtract then divide. Its much faster than looking up a calculator. Sorry for off topic post. I just wanted everyone to know its that simple incase they didnt already know.

What do you mean...the diameter of the aperture...Like the metal case part? or the hole?

And you want me to point it like..at a wall, measure the distance to the dot, and measure the dot diameter? Laser glasses help for that :D

I discovered this with my 10mw like 5 years ago. Have you ever pointed a laser at your teeth near a wall? The spit in your mouth makes cool designs. Here's 2 picture I got with my 200mW...

You don't have goggles? You should get some, burning is so much easier. You can usually use any red goggles that dim the dot, as long as it's for indirect exposure. He said "at" the aperture, as in the diameter of the beam immediately after it exits.

No, I have never tried that... And I won't anytime soon, as I got braces this year. Have you tried shining it through a dark film? It projects a lumia effect instead of a beam, similar to your pic.

you miss understood. I said Glasses help a lot for that (measuring dot diameter) because as you said, I see a faded defused white dot. And yes, they do make burning easier, so you can see its focused to a tiny pin hole.

Yes, you measure how big it is when it exits the laser. Then you measure how big it is on the wall. Then you measure the distance from the laser to the wall.

equation- diameter on wall - diameter when exiting the laser = difference / distance from wall to laser = divergence.
Just make sure your using metric

If I have time ill do it tonight, if not tomorrow.

The laser glasses I own block 200-600nM..Not infrared. This laser, as seen online, has no IR filter. Can you usually by an IR film? I figured if you can buy thin films I could just cut it out to the shape of my glasses, and apply the film..So it blocks 200-600nM and IR.

I dont know about IR films, but you can buy an IR filter and glue it in the laser somewhere. It's just a small peice of glass. I think some one is selling 14x14mm peices somewhere on the forum. Just go look for them.

Well my distance was too far for my tape measure...to not bend..roughly 14ft...

I had a start (at the laser) of EXACTLY 1mm. and about 13ft 10" it was 2mm. To my glasses the dot was larger, but to be honest I think my glasses is showing the dot and its glow radius. Because the dot was like 4mm and the beam was 2mm. A beam doesnt grow 2mm in 2 inches.

So at closer range...for real measurements...I'm measuring the BEAM thickness not the dot, because really theres a glow radius and I think that would be cheating...

Ill do it tomorrow. With a 2nd person to hold the tape measure. I did 33" and it was still 1mm because it was burning the black plastic i use to darken the dot..and i got a 1mm burn hole in it XD

When you look at the spot through goggles there will be an inner spot that's brighter, and it will be surrounded by a slightly less bright circle. I think this is just a characteristic of all dpss lasers. You have to measure the outer circle too to get correct divergence. If you dont it will be way below spec.

Sorry about the misunderstanding, it sounded like you were saying, "goggles would help". :)

Wow I must have goggles that are too strong; I only see one circle.

Personally, I think IR filters are completely unnecessary...

Hmm my goggles are from wicked lasers so they're pretty good. During the day outside I can't see the outer circle, but if i go inside I can see it with my goggles on.

I plan on getting lighter goggles, the ones I have just work too well... It gets hard to see what you're burning, and when I shine the laser through, I get absolutely no visible light coming through.
