So far, I've bought 5 wheels from ewheels.com. 1.ks16s 2.mten3 3.msx 84v 4.mcm5 5.msp 2500w The only issue I've had out of 5 wheels was a random wire in the msp. It was rubbing on the cooling fan, I moved the wire slightly and secured it, problem solved. Each wheel has been great, my favorites are the mten and msp. When I sold one of my wheels, ewheels made it super easy to ship to the buyer. The owner, Jason, has thrown in some extras every time I came back to make another purchase. He replies quickly for any issue and provides great customer service. Since the company is based in the United States, shipping is always quick and affordable, especially for 40+lb packages.
