Cable is only 100mm not 1000mm
I bought this just for the supposed 1000mm cable it advertises. I didn't even need the board. It came with a cable about 8 inches. I tried to "talk" to NEJE but they barely speak English. 3 times they aid the were sending me the 1000 mm cable and 3 times I got another board with a short cable. Just be aware that this has a very short cable, maybe 8 inches and the customer service is terrible. Also takes about 3 or 4 weeks if it isn't in stock, which all 3 times it wasnt, then I receive the wrong thing anyway. The 20 watt laser I bought from them does work well though, however I dont have any other lasers to compare it too.
