So, I'm brand new to electric scooters and was very skeptical of purchasing from ewheels at first, given the proliferation of scooters available on Amazon and elsewhere. However, after reading a few reviews of their customer service I decided to take the plunge on an expensive but well worth, Turbowheel Dart. Of course, nobody expects or wants to have an issue in which they'll have to contact customer service, but in my case I had a problem with the back-tire valve, but Jason promptly responded with a guide on repairs as well as shipping of replacement parts. I'm incredibly satisfied with the service they've provided, and feel thoroughly assured in future interactions with ewheels!
