So far, I have bought a scooter, a unicycle, and side pads for the unicycle from eWheels. I could have gotten any of these items from Amazon just as easily. When I say "just as easily" I mean that as a compliment to eWheels. Its service was just as prompt and smooth as what I have experienced from Amazon. That said, then what's the difference? I experienced no problems with any of the items I bought, however I feel that if I had (and I feel I probably will in time) I can reach out to eWheels and get parts and advice which I know I cannot through Amazon. I researched my purchases extensively before pulling the trigger. As a result, I feel confident that anything I buy from eWheels is of good quality. Judging by what eWheels advertizes on its site, I feel that eWheels cares about the quality and performance of the product it sells. Any regrets about my dealings with eWheels? I have to say, "yes". I do regret that eWheels does not have an outlet here in the Southern California area where I live. It would be very nice to be able to drop in on them and have a hands on look at any product in which I am interested.
