"The product package looks undamaged and i received all the parts but after i connected the protoshield, i realized that the protoshield does not have a bluetooth port and then i checked on this website and it's now clear that i have received the older model v3 which does not support the bluetooth module. Also, there is a huge design fault in the v3 (which i am not sure if it has been fixed in the v4) but there is a pin short-circuit connection between the bottom pin soldering of the shield and the big USB port. I have attached a picture here: https://imgur.com/a/RY8B7fB
I have ordered another board from Amazon but it arrived with the same problem!"
"Quick shipping and well packed."
"Works perfectly. Shipped much faster than expected"
"Well packed ! Have to test now !"
"excellent service item arrived at time in perfect state ...thanks"
"un très bon suivi des commandes, une grande écoute et un grand professionnalisme.
TPU et ABS de grande qualité, on ne peut que recommander!"
"Great seller, really cared about our purchase "
"One item (robotics shield) was not sent until I complained.
Another item, which is clearly listed as having items like breadboards and potentiometers etc, did not come with them. Only to be told that even thought the description and table states they are included, the first picture in the gallery didn’t show them so they are not included.
The robotics shield had the numbers or trace wrong (you decide which one). No instructions at all.
The servo in my robotics arm is seized and doesn’t work. "
“Hi Dan,
I'm so sad that you did not give me any response to my solution.
Thanks for letting me know your idea.
For the misunderstanding from the listing, I'm glad to issue you a proper compensation, and I've asked my sales team to adjust the listing to better one.
And for the connection issue, maybe you can feel free to check this wiki link:

"Even though I had some problems in the beginning the support was able to help me with my problem with a really fast response time of 1-5 hours average. "
"I've been buying various electronics from SainSmart for years, mostly Arduino-compatible stuff. They always have great pricing and good selection. I've likely purchased over $1k worth of stuff, including likely over 50 Arduinos, over the past 4 years. I've never had any snags - until this last shipment where they accidentally shorted me 3 dual relay boards. They made this right quickly and sent me 3 more."
"Fast and correct delivery and quick replies on request."
"out of stock product was accepted "
“Dear Ramakumar
Thank you for your purchase on SainSmart.com
Due to some system glitch that the inventory of the discontinued item has not been synced into the current inventory while you made the order.
I've tried my best to inform you, refund you, and provide a $10 gift card to you as compensation.
Sincerely apologize again, and sincerely hope this did not bother you a lot.
Thanks again for your business and we look forward to serving you again.
Best regards,
Yako”
"First of all waiting weeks for a kit to arrive, only to have it missing several pieces. Having to prove I wasn't lying, takes pictures of my package and showing which pieces were missing, waiting a long weekend, being told my shipment is on the way, knowing I will need to wait several more weeks. I hope they have corrected my missing parts."
"Great fast and friendly service!!!"
"I’m completely satisfied to the product and delivery service."
