"I thought that Sainsmart is a sketchy online store, but after ordering from it, I actually got what I wanted!

Their products work well, and fit with my project!

Shipping is as expected, it took about a week, not like a year or two.

What they delivered me is accurate, and they have included freebies too!"

"I purchased the SainSmart Genmitsu CNC router 3018-MX3 Kit on 7-9-2019, after getting it assembled and operating, it developed a problem in the controller board at which time I contacted customer support thru their email address. After a few hours I was contacted by their support to which I explained my problem, they in turn gave me some test to perform and requested pictures of problem. After sending them test results and pictures, it was decided that they would send me a new board. Yesterday I received new controller board and a replacement limit switch which caused the malfunction of the main controller board. Their service and follow up has been excellent, I would highly recommend them as a seller."

"Just purchased a Sunsmart Ender 3. I am using Cura Software and the 3D Prints are perfect. I purchased a nozzle kit directly from Sainsmart and received in 2 days and received. Great customer support I am planning to purchase a second printer in the near future and it will be a Sainsmart. "
