"I had ordered an 8 Channel relay and needed to return it due to some relays not working. I ordered it from amazon and was outside the return window. I contacted customer service explaining the problem and they replaced the defective relay module immediately. All company’s should be this easy to work with!! Great company and excellent customer service!!!! "
"Our Company processed a major order for a networking project through Sainsmart. Lynn worked extensively with me to provide pricing, answer technical questions about the product, and provide updates on the order fulfillment process. Overall, an exceptional customer service experience on all fronts. Keep up the great work Sainsmart!"
"Had a missing screw, they were on it. I really could have just gotten one locally but they insisted"
"the CNC is pretty good for the price, the plate have a small problem of horizontality but it's not very disturbing. Easy to build, the customer support helped me a looot for the computer part : software, creating files, etc... Thank you very much for your reactivity and your patience !"
"I bought some items on a buy one get 3 free sale. They had several interesting items available for that deal, and an lcd display for Arduino, crimp tool for RJ-45 and RJ-11, and cases for raspberry pi 3 and zero caught my interest. Unfortunately, shipping was a bit too rough on the display and it arrived with scratched screen and bent pins. The crimp tool was not working right as if something didn't line up right, or a tolerance was too tight. But I really like the cases for the RPi 3 and zero, even though the RPi 3 B+ didn't fit as the case was advertised because of the RPi 3B+'s POE header. This clear case that comes in other colors and has a snap-in spot under the top for the camera has the name 'oneinninedesign' on it. I was hoping I could send just the screen and crimp tool back and choose other items. I emailed customer service about the damage and potential defects, and they responded that they would give me full credit for the order (the display was the buy one part of the deal). I was surprised and happy about that.
I have since then ordered another pair of RPi zero cases in clear that look very cool on the zero v1.3 models before the zero W v1.1 came out. I always buy Sainsmart's 2-channel and 8-channel 5 volt relays for my Arduino/RPi home automation project, and have always gotten great service from Sainsmart."
"Perfect service. Fast reply, fast shipping and excelent support. I'm very happy with soldering iron :)"
"This is my second Ender 3, it showed up two business days early, and has slight upgrades that make a world of difference. Very happy to expand my printing capabilities.
This one came with a loose X-Carriage. I contacted support and was quickly provided with two movie answers to my problem. I was able to quickly tighten the carriage within five minutes and the first print after balancing the bed came out smooth and precise."
"Great, consistent quality and fantastic assortment of pigmented TPU's to choose from. Spooled over 10 miles of TPU through my machines, very reliable. Excellent customer service and very fast shipping as well. Highly recommend to any advanced hobbyist or small production shop."
"Delivery as promised. Machine as promised."
"One of the holes in the plate was missing.
Assembly went easy. Software control also works well."
"Excellent product selection at competitive prices, Prompt delivery, No Fuss web site! This all amounts to a great experience.
My only complaint is not being able to use my preferred payment option of PAYPAL but everything else was excellent.
Very happy with the products (CNC ROUTER) and an additional laser head (bought separately). It was all well packaged and arrived safely in Australia very quickly. Offers for discounts are good but might have been better to have been presented when I logged in to order next item rather than a separate email but all good! Just lucky I saw them before buying the extra items :-)

"If you are brand new to 3d printing, doing your research and thinking which printer to pick you can be confident in SainSmart's ability to help you out/respond quickly if you have questions. When I received my Creality Ender 3dPRO and put it together I had several questions in which I could not find answers to. I opened a ticket/requested support and SainSmart was quick to repsond, pleasant, and very helpful walking me through each issue step by step until I was printing without issue. Thank you SainSmart!"
