"They helped me with a replacement part. Very fast and responsive. Highly recommended."

"About a year ago I bought the mini cnc 3018 pro and it's been great.. machine paid for itself in Christmas gifts"

"Customer Support is great to work with and their Nylon+ Carbon Fiber Filament is one of the best out on the market!"

"From day 1, the communication was extremely good. Explanation about the way the package would be sent, responses on some quality issues with the product itself, and the aftersales pro-active handling.

As the former head of a global support organisation, I know how difficult it is to keep customers happy. I think SainSmart has the right people and the right attitude to do the job.

It was a pleasure to deal with you.
Best regards and stay safe,

"Surprising fast delivery with everything that's going on. Will come back for more products!"

"I had a roll of filament that was exhibiting weird behaviour when extruding so I contacted support with pictures and they quickly sent a replacement roll free of charge. Great customer support. "

"Awesome service, beat Amazon on shipping. Controller board was great."

"I have been extremely pleased with my 3018-pro purchase. I have to admit there is a bit of a learning curve but the support staff has been very helpful. The response has been both prompt and supportive. Thank you."

"Of all the places I thought I would find the right Bluetooth keyboard for my iPad, I didn't expect Sainsmart. Good on them for bridging the gap between me and LTC."

"I bought something and they sold to someone else"

"Great service speedy delivery"

"Ordered the SainSmart 17 DOF humanoid robot and upon receiving the package, was missing a few pieces that was critical to the project. Contacted CS and got it resolved with them sending me some extra parts. The whole process took almost two weeks, but as long as you persevere, you'll get what you need. "

"Thank you SainSmart for all of your assistance. I installed the new board and associated wiring and low and behold the laser works perfectly. I have not yet tried the spindle but will In not the too distant future. Again thank you and your team for the awesome customer service and the free replacement control board. Please extend my thanks to all involved.All of the folks at Customer Service are great. They are very fast to get back to you and do not hesitate to involve their technical team in assisting with programming and electronic issues.

Keep up the great work."

"I was unable to figure out how to correctly wire the Mach3 controller to my VFD. I presented the problem to SainSmart support including the manual to the VFD (that I had purchased from someone else) and they almost immediately replied with a wiring diagram. I will definitely keep their URL in my favorites!"

"Every product i've ever gotten from Sainsmart has been amazing. I've ordered camera's, CNC Routers, laser cutters, and everytime they go above and beyond to make sure that i'm well taken care of (and everything works great too!). Could not recommend them more highly."
