Service
I can truly say service was great .

Fast
Great tech support and very fast shipping oh and the new board works great

replacement board
The board which came with my Prover had a loose usb port. A replacement was sent quickly and works great.

Upgraded Control Board
You just cant get better support from a company than you get from SainSmart! I bought my old control board almost a year ago (without using it as I have the MX3) and finally got around to upgrading the spindle to the 20K RPM one. Well, after a single use my Grbl Control Board stopped working. That same day (after troubleshooting things) placed a support ticket (it was after hours for the SainSmart team) and the very next day I had received not only confirmation of my support ticket (along with a set of trouble shooting tips) but also a notification that a replacement was on its way (the trouble shooting steps were the ones I already did). Fast-forward about a week (I had the 300W spindle upgrade I was waiting for) and I now have my MX3 changed to the Grbl Control Board and everything is working out extremely well. Cant recommend this board enough as it was a true drop-in replacement and functions perfectly.

Good quality and great customer service
Have the 3028 for a while, great machine really does a good job. I only have a minor issue with the spindle mount, I contacted customer service and they were very friendly really responsive and I could tell from the get go that they were really trying to help. They walked me though few checks on the machine and at the end they send me a new replacement piece in a timely manner, I couldn’t be happier with my machine and the customer service.

Happy!
I own a 3018 prover. I have two other machines that I want to upgrade for consistency. I am upgrading because these controls work well.

Very pleased with the quality of construction
Purchased this to switch controllers on an earlier Genmitsu 3018 machine. Nothing wrong with the earlier board just that it did not have an external controller port and was the Mach3 version. This one is a direct sub for that module and changing it out was truly plug and play. Excellent value - it comes as shown so you get the base and shield too.

Excellent service
They were contacting me to resolve the issue. Very impressive.

great GRBL controller
Probably my favorite GRBL controller at this current time

Hat alles Prima geklappt
