    Excellent quality was shipped within 3 weeks. Works very well it is slightly fragile, so handle them with care while using it. Its very bright has a clear line. Can see it clearly at night. I haven't gotten any cons about this, overall everything I was looking for in a product.

    The bad: The push button died suddently after 1 week of use as laser pointer, and after 3 weeks a sot-23 component shorted draining 80mA from batteries even if the laser was not being used. The solution was to remove the sot-23 component and to replace pushbutton, (The laser itself and the to be... Read more

    The price is fairly good, the laser does emit a nice and uniform blue/violet color. I've bought 3 laser and all of them are the same build quality and color. Some of the components on the PCB needed to be re-soldered. Inside of the laser diode (when de-screwing the lens) the chips were sometimes... Read more

    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. Pretty hard to focus, you have to heat the metal part to unscrew the lens, because it is glued. It can't burn even a... Read more

    Easy to setup, switch already attached, 3v power and a decent focus of the laser. Laser does not appear to be hot or unstable. Good for play an quite powerful. Does not appear to be focusable, it seems to be "glued on the module". Low visibility and poor quality, Works with 3V But for i... Read more

    * Powerful laser with 3V power supply and switch attached. * Fast startup, high UV emittance. * Very good where UV laser light is needed. * Focus ring present, but fastened with glue. * High divergence. The laser does not produce a spot, but more of a bean-shaped point. * Low visibility, this is... Read more

    Nothing more - nothing less. Hwat u see in the picure, is what u get. Rather poor buildt quality. All components sould bed resoldered for smooth operation. My laser was unstable until I resoldered all components. Extremely poor packeting from DX, and the laser casing crushed other items in the of... Read more

    Cheap laser, with control board, spring for battery and press-button, all in a simple but usefull container. This laser was ready-made for some kind of laser-flashlight. It comes without manual or even a simple explanation of where to connect the wires. Luckily someone else has put in a review I... Read more

    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. Low visibility. Not a surprise as this is a near ultraviolet laser. In the dark the a... Read more

    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! Epoxy at the diode/Driver. But you it... Read more
