I've purchased two inmotion electric unicycles from ewheels (the v5f+ and the v10f, both as one of the first available in the US, thanks to ewheels taking pre-orders). My husband has purchased his inmotion v8 from ewheels; he also had an easy time purchasing on the site. DELIVERY: Both wheels arrived earlier than original estimated delivery dates and in perfect working order. PRE-PURCHASE CUSTOMER SERVICE: First off, the owner, Jason participates on all the electric unicycle forums giving tips and pointers (super helpful for anyone new to the wheel community). Jason answered multiple emails, which helped me decide on which wheel to buy (needed to perform well in the rain with minimal splash so my nice work clothes don't get messy, but be nimble enough for super crowded sidewalks). WARRANTY AND POST-PURCHASE CUSTOMER SERVICE: I'd rode my v5f+ an average of 5 miles (sometimes as much as 8 miles) for over two years when it just stopped working; I was able to send it back for repairs at a reasonable price. The repair was painless and pretty quick. RECALL FOR THE V10F: The V10F models had a company recall; Jason emailed everyone who'd purchased a V10/V10F to let them know ASAP and also notified us that he would be sending recall pre-paid shipping labels in the next few weeks. EXTRA AWESOME - ewheels insisted that the manufacturer throw in additional battery protection, so their customers would have even more protected from the battery issue that sparked the recall in the first place. The total time it took for me to send back my wheel and get it back was just under a week (California to California ground shipping, but even still, that is VERY fast). I've recommended ewheels to a tons of strangers who ask where to find out more; I couldn't be happier with my ewheels purchases and the excellent customer service from Jason and his colleagues.
