My name is Mert Oztoprak.I live in Turkey. I have ordered 30 pieces of Solarbotics RW2i Wheel on April 25. I received them on 28th. I was busy for some time, so i could try these wheels 1 week later i received. Result is very sad. I can surely say that, these wheels are faulty. 17 out of 30 of these wheels cannot be mounted to motor shaft properly. I could mount some of them by pushing very hardly, but wheel looks tilted. I think, center of these wheels could not be drilled precisely at right angle. My english is not very good, I hope i could explain my problem. Here is the photos i took:
You can see the tilted wheel:

I wonder how pololu can help me for this problem?
