It was very easy to find parts

Smooth transaction and fast shipping.

All good, thanks.

Poor description of the product. The listing implies that i would be receiving the motors and the controller. After purchasing i realized the last number listed was for the motors only. Still a decent deal so I'm not too upset. Just disappointed.

Really easy and good

Great experience so far.
