"Product shipped on time, even during the pandemic! Unfortunately, it was defective, and it was the last one in stock. Hong in customer service was awesome and was able to fully refund me for the defective product. I will definitely return to SainSmart for future purchases!"

"Did never receive anything."

"Fast shipping. Did price match after I found better price elsewhere. "

"I recently got a 3018 ProVer from Sainsmart. The machine arrived when expected and was in excellent shape. The instructions for completing the assembly were very clear and the parts were all well labeled. (It took me about an hour to get the machine together and running test operations.)
I had 2 separate questions for the support team (not related to the delivery) and they were very responsive in both cases. I wanted the ProVer because it comes with limit switches in all 3 dimensions and an emergency shut off switch just in case anything goes wrong during an operation. They all work quite well and I have completed over a two dozen part designs in the week since I got the machine. "

"Bought from them a few times. Very good prices and quality, delivered on time, and they provide excellent customer support if it is needed. "

"Great attention, excellent post selling service"

"fast delivery. I haven't checked the product yet"

"Shipped quickly. Packaged well. Made it from China to East Coast US via Hong Kong quicker than item I had ordered nearby. Only thing I would mention as a negative was the package arrived in April 2020 with a coupon that expires in December 2019. Not a big deal to update to newest firmware."

"Sainsmart helped me with a fan issue on my 3018 motion controller. A new fan was expedited to me and I received it in a few days. Plenty of follow up from customer service to make sure my issue was resolved."

"I bought the Genmitsu 5040 Laser Engraver with plans to start my small engraving business. I had an initial issue with my laser but Sainsmart quickly helped me remedy my problem. Quick response time and quick action to ship a replacement part - that's great customer service. I will definitely buy again from them when I'm ready to expand my engraving business.

"

" Had a bad customer care experience at first. But few days later out of a blue sky a high up guy from Sainsmart contacted me to make things right. And he did. I will use Sainsmart again, and would recommend them. Very happy with product and aftersale care. "

"I was very satisfied with all,Good delivery, quick response and service.I appreciate you ！"

"I received my SainSmart Ender 3 back in December. It was affordable, at the cost of some quality to the parts, but that's why it's touted as an entry level printer! There are lots of upgrades and other parts online and a big community that can help with what to get. I've had a couple issues both hardware and software, and SainSmart has always been there to help, they've even sent me a new motherboard! They've given me plenty of support and guidance to get the printer fine tuned and running smoothly over the last six months, and I know my next printer is going to be from them!"

"I have a Sainsmart Ender3 and a Sainsmart Gemitsu 1810. Each came with all the parts and accessories promised in the assembly instructions. Each worked perfectly the first time. What could be better?"

"good support and fast delivery.
Very good quality products"
