Received my set and everything looks fine. Of course I haven't used everything yet, but I found 2 faulty components: a stepper motor and an ultrasonic sensor. The rest seems fine and works really well for me. So I can't give 5 stars but Smraza has done an excellent job with the libraries and the PDF (online or on CD), it's well explained, the diagram is clear and the examples are very helpful. I love it!
