Review of o-like's 400mW bluray laser found here: 400mW blu-ray 405nm laser torch /adjustable/waterproof [OL-405T-400] - $102.99 : Welcome to O-Like.com, Your source for laser products
It cost about $100 and it took a total of 26 days to arrive in southern California from the day it was ordered.
Ordered: Dec. 20th 2010
Shipped: Dec. 29th 2010
Left China: Jan 10th 2011
Arrived US: Jan 15th 2011

Stats of the laser:
Metered >380mW
Waterproof: yes
Polarity: Case Positive
Battery: yes [Trustfire 18650]
Charger: yes [100-240V]

It arrived in a box with an instruction page, charger and a 2400mAh Ultrafire 18650:

Here's a comparison with a PHR at 100mA:
Beam:

Dot:

The waterproof glass has a greenish AR coating, and this is the same coating they are using on the red waterproof lasers in this same host.


It metered at just over 380mW:

A video of it cutting electrical tape, lighting flash paper, etc....

Waterproof test:


Overall; it's not quite 400mW, but I think a focusable 380mW waterproof 405nm laser for $100 is a great deal.

Great Review. All these positive Reviews Have made me just buy one.

+1

Nice review. Mine will arrive today in the mail.

Thanks for the review with a meter. Will be ordering one within the next week!

Exellent work. +1

Mine O-like 405nm is crazy overspec then. God I hope it doesnt blow up

Thanks for your review! I could not help but order one of them. My meter shows exactly 350mW on it, so its like O-like promised. It came with a micro-charger and a grey "UltraFire 2800mA" and a nice black present box. In the box was a small slip unlike yours, saying "Respect its duty cycle, so don´t operate continuously more than 1 minute every time", which leaves open hop much time I have to add between the minutes of use... Anyways, on my own risk I extended its use to 3 minutes, and it got only slightly warm. As also the host gives me a good feeling holding it and looks great, also I can recommend buying this. BTW, price raised to $109 now, but still worth it.

I grabbed one of these too, after reading pretty much this whole forum. It came today, and I am LOVING IT. It's black, instead of the graphite, which is my only complaint. I don't have an LPM, but I got it to do all the cool burn-y stuff, like lighting fireworks and matches. I wrote up a full review with video on my blag HERE.

On my compurer´s screen it looked black from the beginning on all pictures, so I don´t complain...

I can see that now that I know it's black, I guess I just got my hopes up!

It's a great unit no doubt. The duty cycle is more like 4-5 minutes on/ 3 minutes off. @ 5 min, the heatsink on mine justs starts to get a little warm. (maybe 90*F)

i'm so tempted to get this laser, this is very cheap for a 400mw, right?

yes verry cheap

Anybody of you guys got one with a loose lens? I noticed that the focus changes by itself if I turn the whole pointer (around its axis), then I found one lens is shaky. Now I need to buy a tool to open the top to get access to the lens. I don´t want to send it back because such a minor flaw. Anyways, its my favorite pointer so far.

I don't have a loose lens, but your's can be tightened.
You don't need a tool to get into the area where the focusing lens is, just unscrew the top piece.
And when you get to it, you can easily adjust (tighten) the lens nut with a thin flat-head screwdriver.
You may need a spanner-wrench (or a pair of tweezers) to unscrew the lens-holder.
Here is a pic of the inside of my o-like 405s head:

Ash, thank you. You are absolutely right, now I wonder why I did not see this by myself before. I guess I am becoming old. About the white stuff around the lens-system of your pointers head, it looks like glue. Did you put it on? My pointer does not have any glue or similar at that place.

Now I have this pointer quite some time. Next I want to buy something small, with a 14500 cell, but same specs. Any recommendations? But this is an off topic question... :-)

I believe the white stuff is thermal grease and the laser came like that, I didn't put it on. Not sure if it's grease or glue though as I haven't touched it.
OK. So you want a 405nm pointer with the same (400mW + focusable + waterproof) specs that uses a single 14500 (3.7v AA size) battery.
You are not going to find this in a production pointer. It will have to be custom made by someone here, and not many DIY-hosts are waterproof. So you may be out of luck.
If you had an LPF member make one for you it would be relatively expensive as well. I'm guessing over $200.

The 14500 then I will do as an own project when I ever should find time to do so. So its not that important right now.

Yesterday I took a flat headed screwdriver to fix the lens. I accidentally screwed it in too far (there was not a lot of force needed), with the result that I could not focus it anymore to infinity. I then decided to screw it out all the way to inspect it. I then found that there was not a single lens loose, but the lens-system (or how to call this optical package?) was loose due to some tolerances in the threading. Then on the side of the waterproof flat glass I found some of the white stuff (its kind of soft glue, its purpose is to hold the lens system in the factory adjusted focus place; at least I think so ). Apparently it was a bit too less of this stuff, so the optics loosened itself.

Now I just screwed it in to the right position hoping it will be ok. Otherwise I will use some glue myself later on. I am quite satisfyed with the result now, because its OK, and because if its not OK I can fix it anyways easily....

Thanks.

Semi-stupid question: It's the brighter of the two in your pictures of the beam and dot, correct?

Yep it is (the brighter dot, not a stupid question).
It only looks significantly briter on camera. In person,.... the visibility difference isn't much more than a 200mW bluray.
But it burns really well, and a waterproof 400mW bluray for around $100 is a relatively good deal.
Also, I have verified that this model will survive deeper than a standard Rayfoss waterproof.

thanks for review.

noooo i mean... yes. your review was too good, just ordered :P

Got mine couple days ago and I LOVE IT!!!!!

This was a good review! I am considering getting one. I have a couple of questions. Is O-like similar to optotronics? Are they related? Also what gets my attention is the water proof. When i vacate i like to scuba dive and i was wondering which lasers are water proof, strong enough to burn things but survive depth in water?

I haven't been brave enough to put any of my "Waterproof" lasers in water, +1 for the braveness and review

How visible is your beam in the day? Night?
