For curiosities I invested in a twin boost dragon, I say, a small green laser Cheap is nice, verdict of shit and shit is as unspeakable stuff, slap in the laser After 1 week, guaranteed non-existent, so I put the disassemble to see how it's done. a shame, the son who balladent everywhere, stepper motors not manufacture more than doubtful (there are no two identical engines and one wonders o are the step) son, who plies are inadequate, 11connecteurs on the map, 15 connectors on the water, a short over-water, must all tighten after each use, it is very noisy, 60mW laser power after regis Checker lasercheck home with a coherent, we get 3, 4 mw, 60mW is the power of the infrared diode pass once in YVO4 and KTP is obtained Green 3.4 mw no rgulation of temprature, laser fix with double sided adhesive sive on a piece of fraille not even properly screwed and half of the power passes through the mirrors that are censs THINKING laser and so far, I have no room for everything possible. I finally DCID keep the cash and some matrial and make my own green laser, 100mw rel for wholesale, laser diode infrared 808nm of 1.2 watts mini a good crystal YVO4 the yag being much more expensive and a good KTP crystal lenses of Colima and hop 100mw green laser and rel rgul in intensity and tension especially in temprature (sinks, and Peltier ventilos) all for 1500 euros that is the true price of a naked green laser. therefore résumé I strongly deprecated stuff like boost or mac mah = same shit only the logo change is made by the same box, you may bite into your fingers, no protection against overheating or current circuit, ideal for fucking fire or burn out your gear 2 or 3 passs effects loop, after 2 minutes is annoying to see the same designs, and the worst is that you have very unlikely to have a photo of MODEL, Running boost its old stocks before, so gear improperly stored and rust. I do not even put veusx note on shit, ps rputs the Chinese for their infringement and stuff very very low end, why a change suddenly?
