I've had literally no problems with it. It arrived on time and I am very happy. When I ordered this I ordered my Arduino Uno from the same person so they came in the mail together which was great so I didn't have to wait to use it. The examples on the site it shows you are pretty hard to understand. I got stuck on one for OLED, but that was because I didn't have the library loaded. Overall this is a great product and really fun to learn Arduino and create your own projects.
