When my son first said he would like to buy a Hover board with his Birthday money, I didn't really know where to start. I agree with some of the other reviews, "It's an absolute minefield out there ! " I researched the internet for hours and luckily for me, I stumbled upon Rolab. A very professional website with all the information you require and all your questions answered. As with everyone else it arrived the next day, early enough for me to get it on charge ready to use when my son got home from school. I can't begin to tell you how happy my son is !! I quote " Dad ! It's the best present I've ever had. Its sick ! " ( That means good ). This product is so good, I have just ordered a second one for my eldest son. Apparently Hover board football is the next big thing. Would highly recommend ! A great product and great value for money. More importantly, its Certification gives you peace of mind.
