"I have had a great experience with Sainsmart. I like their products that I have uses so far with the LED Shield and Arduino UNO. I had a small issue that I figured out was a coding problem with some Arduino code I was using from a project that I bought elsewhere but tech support was very willing to help. Keep up the good work Yako."

"I was very satisfied with the product and their service."

"I buy project parts from disparate sources and it's unusual for them to provide this level of communication and genuine care. With my first order they informed me that an entire batch of products turned out to be defective and sent back to the manufacturer - they caught this before it was sent out and helped point me to something without issues. They updated me through the entire refund process. So very good service - they are high on my go to list."

"good service .
excellent
large range"

"Very good feedback and overall support getting the product delivered."

"Delivery was pretty fast seeing as it came from China, and when reaching out to customer support for a question on documentation for one of the products, they were more than helpful."

"it does not deliver at all. I purchased the board and money has been deducted from my account but my order status is ''suspected fraud". I paid the money, i even contacted to some guy named "yako" at customer services of sainsmart but he is not really cooperating at all. he keeps on saying to buy a new one. I guess he is really messing with all this. He once said he refunded the money but when i asked him that if u received the money then why u did not process the order instead of refunding my money then he changed his point saying that he received 0 amount from me. First, he said he refunded then he said he did not receive anything from me???? I guess he is deceiving me, he received the money but somehow managed to get it off the record. I can send u messages for the record.
If you are someone else, then kindly look into this matter, if you are "yako" then don't bother to reply
Thanks"

"The product I order came missing a key component, instead a duplicate of another item that was part of the product came instead. Still in the process of resolving this."

"Bad with out tracking number and with out email getting folowing"

"Thank you very mutch for the assistance e help with my item.. Great service.."

"Questions about the mini oscilloscope I purchased were answered quickly and in great detail. Great response and great products. "

"I ordered a single board computer kit. The initial shipment didn't have all the parts. After an email explaining the problem, the rest parts were quickly shipped out and delivered. All parts worked as expected."

"the delivery was earlier than I expected, and came in good order."

"Delivered quickly and as ordered."

"I bought an arduino board with a TFT shield and TFT + Touch Screen via the Amazon shop. Everything arrived in good shape (some pins of the shield a little bent, but nothing that could not be repaired). I would suggest the seller to ship the pin strip unsoldered or package shield better. My concern was the LCD display but it arived in perfect shape.

I was able to assemble everything in a few minutes and, as suggested on the web site, I contacted the seller for the necessary library. I got an answer in less than 24 hours and I was able, in a day to run the example and start writing my own code (RF power meter).

Good seller, right prices and great support. "
