    Several tests with 5000mW did not give the expected results. With this range, I must pass without problem with the CNC. The product is well finished, with its adapter and converter for EU plug. Great, keenly the first tests. In addition, it comes with the appropriate glasses because the light density is really higher. We can never say it enough ... ATTENTION TO THE EYES ... The work surface is not perfectly flat and can sometimes reflect radiation, the damage would be irremediable to the eyesight. At this power we have long since left the toy stage !!!!

    Shipping is fast in the current situation, received in good condition and good packaging. Product is good quality for laser unit. Cabling is too short and power supply is very basic and rated at max power. Tester module is fine for troubleshooting but I would not set it permanently within the circuit as cabling preset. Goggles are lowest quality, look for something of a better quality if you intend to work more than a few minutes close to the laser. I haven't yet tested the laser on a long run. I can't say if it support a full work cycle or need to rest cooling in the middle... Keep in mind, this is not a real 20W, it uses a 5W laser diode with pulsing to reach a theoric 20W for very very short period of time (ms). There are no 445nm laser diode over 7W and again, 7W modules are typically lower Watt with pulsing.

    this laser works very well. the optical lens is not the best at focusing the laser but after market mods work better.
