I have order numerous times over a few years and they have amazing products. Unfortunately the last time I ordered something, the item did not come. They assured me a refund was coming my way. After waiting a month and nothing, I contacted them 3 times and never received an answer. I then had some promotional coupons in which I can apply to my order. I attempted connection with their Chat Line and left numerous emails never receiving an answer. Finally, I tried to make an order and apply a coupon and the coupons would not work anyway, they were not relevant. Again, I contacted them to no avail.
I am frustrated enough to say be very careful with them. Good luck.

Laptop, cellphone batt have same danger but they are smaller. Keep the hoverboard ""OFF"" when not in use
