"Very satisfied with the product, work like a charm."

"Fast shipping, but micro sd card is bad and power supply not give the right voltage. "

"I have been using Sainsmart for many of my Arduino Projects and have found their boards to be very good quality and they have reasonable prices and shipping costs. I have used their Arduino Uno R4 which is extremely useful with breakout pins with each digital pin having its’ own Vcc and Gnd pins. "

"I like that they have a warehouse in Europe, otherwise you'll have to pay extra import taxes. My TS100 soldering iron got delivered a couple days later and works great! :)"

"My scope came fast enough, thanks for that. The instructions leave a bit to be desired. It does tell me to install the latest firmware and gives a site address, but it's to a chat. It keeps referencing the charger cable which was not included, but they're cheap on Amazon. It also states that it comes with two probes that by the word of the insert are the same. Mine are not, but i don't think the difference is crucial. I did have to wait for my charger cable so I haven't had the time to use it yet."

"I had never heard of Sainsmart before this order, but found it hard to find the upgrade parts to my 3d printer as most places in north america were sold out of the motherboard. I gave Sainsmart a chance as it was the only other seller where i could get expedited shipping from China. I live in Canada and to buy a similar package from ebay would take anywhere from 20-40 days to arrive, where as for $15 I could get 5-7 day shipping from Sainsmart. The package came as advertised and arrived a few days earlier than expected. Was shipping from China to Canada and arrived in 4 days through DHL. Would definitely buy from Sainsmart again."

"Dhl service is painful, we need travel truth the city to get our package, awful."

"Bought oscilloscope, good price, arrived in time. After installation I experienced irregular resets. Sainsmart support responded very good to my support request, and helped me to resolve the issue. It was a good experience!"

"Everything perfect, thanks a lot "

"On time and worked well, great for college."

"Very fast delivery. Top tool
I love it!
Thx"

"Everything was as expected. The only downside is the relatively long shipping time to germany. But that I knew beforehand."

"We would like to resell Sainsmart products.
However, we don't receive any invoices and the ones that we receive are incorrect.
No discounts allowed for reselling the products.
So as a dealer we are not satisfied at all.

"Livraison rapide. Emballage soigné. Fonctionnement OK."

"Ordered a replacement board since I burnt one out with the wrong voltage and shipping was faster than I had expected and was quoted. Part works flawlessly too. Custom support was also very helpful in providing usefull information that provided a solution to an issue I was having."
