"Didn't notify me that my order was shipped until it was out for delivery, then had the same tracking number for both items, but only one item was delivered.
I reached out, and while their response was within 24 hours, it basically was 'oh that part of your order hasn't shipped yet', and then they shipped it to arrive next week when I placed my order two weeks ago."

"I ordered a CNC router, and found it had a bad component on the motherboard. They shipped me a new one as soon as I contacted customer support. New motherboard works great, thank you!"

"I received the 3018 pro as a gift. I don’t know anything about assembling a CNC machine so I was definitely a little worried about actually getting to use the machine.

I was able to get the machine assembled and connected properly to my computer through emailing the SainSmart team. (Lynn). I asked about 20 different questions I think and they were willing to answer all of them, sometimes with pictures. In this day and age where most businesses are lazy, that was pretty damn cool!"

"the place is not bad. I got what I paid for. I was annoyed that I could not add to the order after it was placed. I tried to contact them to add some items to the order and they have absolutely no contact besides a web form that they do not answer until it is well too late to add to the order"

"Great communication, fast delivery, overall excellent service
"

"Saturday night a part died on my Gemitsu CNC circuit board. At 1:30 AM I sent a note asking for help... early next morning before I was awake, a note arrived in my email. It said the part was on the way and a tracking number would be there in 48 hrs. The tracking number arrived Monday morning, and a new circuit board arrived Tuesday! I was floored! I have never received such excellent service! Thank You Lynn and SainSmart."

"Overall the experience was very good. The products were as advertised delivered promptly and the online support was excellent."

"I ordered a 5"inch touch diplay. They sent me a used, broken unit. I sent pictures and they sent me another unit, this unit was also broken and not working. I sent a pic and they refunded my money. I was still out shipping. They have serious problems."

"As always, great value as well "

"good communication and service, I would buy again at Sainsmart"

"I’m just learning about Cnc so A little more information with software would be very helpful!!!"

"I had a problem with the control board and sent a message to customer support asking about availability of parts. They sent me out a replacement board the same day. Top notch service!"

"Good price, quick shipping and excellent quality. Prints great. "

"Filament is easy to print and it seems very durable. Shipping was fast."

"Fast delivery great product"
