My 4040Reno suddenly lost Z movement…
My 4040Reno suddenly lost Z movement control starting halfway the Y-axis (yes, halfway a large cutting.... ). After checking most components without success I sent an email message to support. This was answered within minutes by AI which asked me some (logical) questions that didn´t solve the problem.. After answering them by email again, George from support came online and suggested that the main cable from the controller might be broken. I provided the PN of my machine and received a new cable in 8 days! Again thank you so much for this support. I am pleasantly surprised that you are able to deliver this kind of support on what is probably an entry level machine and I think you may have found the right fit between AI and personal attention. Great stuff!!

No additional freight charge
I purchased a Creality Raptor 3D scanner but it wasn’t available in Canada. SainSmart was good enough to send the unit at no additional charge from the US depot. The unit arrived via USPS and Canada Post without much delay. Even though the prices are not the lowest, I would purchase additional items from SainSmart without hesitation.
Got this as a Christmas gift for my maker husband, he loved all the features (multiple different types of arms, rubber tips, cool light setting, glass magnifier, organizer slots). He said it's the nicest helping hand/workmat he's ever had and loves to use it for soldering and organizing transistors. Win! (Shipping was quick too and the packaging could have withstood a warzone everything was super protected)

Fantastic support
About a year ago, I bought a CNC router from Sainsmart but due to circumstances I was not able to use it untill last week.
I was struggling with a g-code setting and asked for support.
A friendly and knowlegeable reaction was given within a day, also on two follow-up questions. Which is really fast, considering the time difference between our countries. Great experience!
I bought the 700w CNC spindle. After installing I noticed a 0.25 runout (measured with micrometer). I contacted support and send a movie as proof. They immediately replied and send me a replacement (which was ok with 0.05mm runout) for free. I could even keep the faulty one. Top notch customer experience and support!
