I've bought 3 laser and all of them are the same build quality and color. Cons:Some of the components on the PCB needed to be re-soldered. Inside of the laser diode (when de-sc... Read more

    Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:It's a cheap, great blue laser module. Pretty easy to use: just plug a battery on the spring and plug the positive at the board. It seems well soldered, work without any problems. Cons:Pretty hard to focus, you have to heat the metal part to unscrew the lens, because it... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Reliable blueray diode laser module. Not so small beam, as this is a diode with focusing lens - not a DPSS-crystal. But the beam has good and low divergence. Will not get hot, so duty cycle is not a matter here. Cons:Low visibility. Not a surprise as this is a... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Great 405nm Module. This module IS focusable! The lensholder is glued, but if you heat he brass to around 50°C it was possible to unscrew the lens. Remove it completely to clean it from the glue. If it is focused on a small dot, you can even burn things! Co... Read more

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day Pros:Easy to use. Strong build. Cons:Completely NOT focusable. There is a focusable lense when you open it but it's imposible to adjust it, maybe because it's glued, rather than assembled, so it would be imposible to focus unless you detach it, and put a good quality...
