First shipment of these is arriving to users and its performance is rather underwhelming according to laser aficionados.
Beam quality is poor, highly divergent and has considerable astigmatism. Typically these multimode diodes are moderately astigmatic however the simple collimation has no correction. Videos showing this are beginning to appear as well as rather lackluster "burning" performance. With a direct diode laser having the ability to "focus" is essential and this product does not allow this. You get what you pay for. (some people may not even get that!)
