Review: Works well - Seems to work great. Just a prelim test at 6 volts (minimum seems to be 2.2v to turn on) it burned my black mouse pad. I'm not a pro on this stuff but I've never had a 5mW laser able to burn things 12 inches away, but I'm happy with extra power but just be careful this is way more than a typical 5mW laser pointer, WEAR EYE PROTECTION I pointed it at something dark 30 feet away and had to peak over my glasses and it was pretty frickin' bright.
Review: Defective and replacement was also defective - I had bad luck with blue lasers from this seller. I ordered a blue line laser and a blue dot laser. The line laser is very bright, as it should be. The dot laser in comparison is very dim. I returned the blue dot laser for a replacement, but the replacement was likewise very dim. A properly functioning dot laser should be just as bright as a line laser - the internal components are the same. I would be very pleased to purchase a properly working blue dot laser from this seller, and would order again if I thought this was just an isolated incident. But I've now been through the cycle of receiving a defective product, requesting a replacement, and being provided yet another defective product. I am concerned that they have failed to do adequate quality control on their stock, and I don't want to spend time ordering and returning again and again until I finally receive one that works properly. This is disappointing, and also somewhat confusing, as I have also ordered red and green dot and line lasers from this seller and all of them work properly. I will update if the seller offers me a solution.

### ⭐⭐⭐⭐ Yep- BLUE laser!! Burns too!
*by J***9 on June 4, 2023*

Ok- First let me say I'm a novice to diode lasers- burned my fair share of DVD diodes, built numerous working drivers for the diodes, but I still have A LOT to learn about & from diode lasers! That being said- my experience w/this diode goes as such; received laser diode in good time (2 days), figured out that it has a driver built outside the metal housing, & encased in (hotglue?) & shrinktubing, has a glass lenses, will lase @ 7.5volts via wall transformer, a very COOL Blue, NOT Violet, beam! Doesn't burn at this voltage: well- it WILL burn retinas, moist, valuable, & super important unprotected eyeballs... And no, I didn't burn mine- cause I like my vision & took other enthusiasts advice to wear the correct protective eyewear! Thank you for that- cause this laser is BEAUTIFUL, but only takes one careless moment or lapse of attention & it's a permanent regret! So, be as smart as it takes to build & use these things to protect yourself and others! Ok- I wanted to burn stuff, & 7.5v's wasn't showing any substantial damage I could brag on, so I grabbed a 9volt battery, adjusted the focal length (about 7"-10") and eureka! Smoke!! Damage!! Finally my first sign of destruction-albiet it was 5x smaller than the period at the end of this sentence. Hmm- more power!?!= Bigger damage?!? Yep- more power sure did more damage; the driver was enveloped in a dirty jet-black smoke that stunk & proceeded to have me banned to the outside workbench!! The Wife was Not pleased her beautiful oil diffuser smell-good stuff was rendered ineffective instantly! Lessons learned- So- I'm sure my diode is done- housing & lenses still usable, driver is obviously toast- literally. 12volts was too much for it. So I promptly ordered another module- I am going to receive it here any minute! Now, as you can guess I'm going to pamper this thing till I educate myself on the tolerances the diode can safely withstand- like big heatsinks, proper power supply and cooling fans!! Lol! In all seriousness, this is a great small blue (445nm) burning laser that should be respected & used in a mature manner. Not a pet chasing toy to be sure- but it will be an awesome addition to my 5 color laser paragraph display! I rated it 4 stars cause it should come with at least a little more documentation- however, saying that probably just exposed my ignorance! Be smart- be safe. Yes do buy if it fits your needs. It is worth it!!!
