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.

4 year user I’ve used Sainsmart products for 4 years now and stay with them for their customer service. I run my machines around the clock and they are always quick to help me get new and replacement parts that I need.

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.

Satisfaction Guaranteed I recently purchased an L8 20 watt laser from Sainsmart and was having a problem getting it to connect to the computer. I was dealing with Jamie who assured me they would figure out the problem and within a few days they sent out the parts necessary to get the laser working again. I've been extremely happy with the service I've received from Sainsmart and would gladly recommend them to anyone interested in purchasing a laser. Thanks again Jamie, Steve.
