So I thought these "hoverboard" or Electric Scooters got recalled, but it looks like this is a new model and they made sure to have huge UL 2272 stickers on them. I googled the listing and it's a new certification just for these which covers all of the electrics and not just the battery.
Other than the upgraded electrical specs, I'm not sure if there have been other changes with the T1. It lists:
Aluminum Alloy Body
Battery Life Indicator
I'm not sure if the old ones were Aluminum Alloy? If anyone had one of the old ones, I'm curious as to any other differences. Anyhow, they are at Frys B&M only this week with sales tax off if you have a promo code. Sign up here if you don't have one.
