"I got a DDS 120 with a DVD to install the software. My computer does not have a DVD drive so I went to Google for help, The software I found was not working so , I send a note to customer support and they got me up and running in less than 24 hours. Great service!"

"Somehow my first order was lost in shipping. I contacted Sainsmart customer support and they immediately sent a replacement item which then arrived on schedule. I was impressed with how responsive customer support was in resolving this problem."

"I purchased 1 axis programmable motion controller ST-PMC1. product price and delivery is very good. however, manual could be very much improved and connection diagram should be added to it. I could not figure out myself how to connect it properly. internet search did not solve the problem. so, I had to contact sainsmart support online. they responded next day (time difference makes delays :( ). with help of manufacture engineers it was eventually solved and I got motor moving. bottom line is: product is good. priced nicely. if sainsmart could improve manual, having written in understandable english and provide connection diagrams - it would be very unbeatable product, I think! :) overall - excellent, as sainsmart tech support is responsive and they are trying their best to help you out. "

"Good quality products, fast delivery, will definitely buy from Sainsmart again."

"I've bought a sainsmart pro32, and I couldn't figure out how to update the firmware (online tutorials didn't help), I wrote an email to their customer support, and got a response after few hours, I explained my problem and got redirected to a technician that eventually helped me.
Email exchange was very quick, and my "handlers" were very polite, their English wasn't perfect, but my isn't either, so I can't complain:)
I recommend this company!"

"I've been told and have experienced superior quality in all electronics and filaments but when a problem arose, the service was top notch. I'm looking forward to using SainSmart whenever I can."

"Good day,
As I have now received the return of my money this morning I'm able to respond with my feedback.
I have nothing but the highest of praise for your well managed and competent company.
I'm sad that the border gave grief in not delivering my purchase but the professionalism and honesty SainSmart showed me dealing with the situation was second to none. They offered a couple of solutions and followed through immediately with the one of my choice.
I look forward to again dealing with SainSmart in the near future!
"SainSmart" ......Your the best!...........Thank you ever so much!

"The arm comes assembled. I was able to power all of the servos in this arm one at a time with just the arduino power. It works great!"

"They were always so nice when I needed help. They sent me a new pen when mine broke. They are always so polite.Thank you SainSmart.

"This device gave me at once and very good reproducable information about environmental pollution in a wide range. Exemple: Air purified after rain contained only 1-2ug/m3, whereas after a 33Celsius- hot evening some 100m close to a main road, values rose up to continuously 40 ug/m3 for the rest of the evening. Best room was my childrens cellar - not in use for some days, so eventual pollution had settled down to ground : PM2.5 monitor-indication 0 - 1ug/m3. Until now I use this room as a reference. Big astonishment after grilling some steaks in the kitchen: values in neighboured living room rose to 120ug/m3 for about an hour and until opening the windows.
For comfort I use some computer USB-Power Banc, holding more than 20hrs service.
My studies go on with this excellent device..

"Good product & efficient service"

"A good customer experience is not due to the experience when everything goes well, but when something doesn't. It is only then that the company can really shine. Sainsmart does make an effort to ensure that during times when there are problems, they still go the extra mile to make sure that your problems are adequately resolved. "

"I have always had good experiences with Sainsmart. They have the goods I want at reasonable prices. But they only use US dollar prices and their order tracking is hit or miss.
So, will I continue to shop here? Yes, of course. Will I ever be completely satisfied? No. But I'm hard to satisfy. "

"I like how they active they are on emails and how constantly they send emails to update on the status of the purchase. Nevertheless, the parcel that was dated to arrive on 7th July arrived a month earlier which is what customers would love! Simply a superb first experience with Sainsmart.com"

" I got two Camera Modules for Raspberry Pi -101-40-102- and both are funktional and do their job as expected; the price was very good (2 for 1 promotion) and I got it in two parcels 3 and 4 days after the order. Communication was very quick too (one day max.) and therefore I will do in the future more transactions ;-)"
