I bought the 3018ProVers2 with Controller I bought the 3018ProVers2 with controller from Genmitsu. Fast shipping and everything neatly packaged. Unfortunately the controller was missing from the accessories. Short email to the manufacturer and 6 hours. later came the following answer: Sorry, please provide address and telephone number. We will check the purchase and send you a new controller with accessories. 8 days later the part was there and everything works perfectly. A great service without any ifs and buts... GenMitsu gladly again... Erwin H.

Excellent customer relations by Sains Smart A communications breakdown somewhere in the system meant that I wasn't aware that the courier had tried to deliver my laser engraver. Sammy, customer relations at Sains Smart, asked for some details and quickly decided to send me a replacement - which took only a couple of days to arrive from China. Very well done, I couldn't have asked for more!

Excellent Very good, fast delivery time, the products are very well packaged. The products are very robust and work perfectly. Great at SainSmart, keep it up like that.
