Turn key happiness!!!
Personally, all of the interactions with the professional experts at SainSmart have been top notch! They have always answered my questions in a timely manner and have made suggestions to improve my experiences with my mill. I couldn't be happier!
Great filament good ptice
Good filament. Worked fine.
Helped with discontinued laser
Had a discontinued laser that wasn't updating firmware and tried everything. Contacted customer support and Jamie helped me make it work! Great customer service experience.
Amazing response!!
Amazing response!! I bought a set of clamps by mistake. I'm very very new to CNC and I bought CUBIKO a week ago. I LOVE IT. Super awesome tool for your desktop. Strongly recommend to hobbyist and ++. Anyway, even I bought by mistake, I don't use them so I contacted to SainSmart, they give me shop credit for the price immediately and said I can keep the climps! What generosity and kind response. Once again Thank you SainSmart staff and their great products!!
Nice support
good warranty
One of the stepper motors on my CNC router broke down quite soon after delivery. But Sainsmart replaced it free of charge and very quickly.
Excellent Customer Service
Initially I received an unrelated product to the one I had ordered. I was a bit dismayed as I imagined there would be a lot of buck passing between the supplier and the courier company. However when I emailed SainSmart customer service they immediately reprocessed my order without any quibble. First class service and I would have no hesitation in buying again from them .
Thank you very much
Quality products and service
I had a slight problem with a purchase that I made from this company on Amazon. They addressed the problem with care and ease, ensuring that I was completely satisfied after the interaction.
Excellent customer service
I recently purchased a CNC machine from SainSmart, and I’ve been genuinely impressed with the service. First off, their pricing is very competitive, which made the initial decision easy. But what really stood out was their customer support. I had a small issue, and their team responded quickly, and professionally. There was no back-and-forth frustration—just fast, effective help. They went above and beyond by sending me a complete new set of collets without any hassle, and they made sure it arrived quickly. That kind of responsiveness and care is rare and really appreciated. Overall, SainSmart comes across as a reliable, customer-focused company that stands behind its products. I wouldn’t hesitate to recommend them. Thank you.
quick delivery and a great machine
The machine and all accessories came very quickly. Packaging was really nice. The machine is already working 8 hour shifts and runs smoothly. I am sure we will take a second one very soon:))

I had a technical issue with my first unit, but SainSmart's customer service was incredible. They sent me a brand-new replacement machine right away. The new unit is working perfectly for my PCB prototyping and CNC projects. It's rare to find a company that stands behind their products like this. Highly recommended for any maker!

Great support team that strives to help their customers get the most out of their products. I very much enjoyed the outcome as much as the process.

Better than expected.
Good quality at a reasonable price.
George took customer service to a level I never expected
I initially contacted Sainsmart customer service in an attempt to get help with a machine that my company had purchased from a different manufacturer after 5 months of getting nowhere. George was not only informative and helpful but he also took customer service to a level that I would have never expected. With a customer service representative like George I would confidently recommend Sainsmart to anyone!!!!!
