Bought hoverboards for my grandchildren - 6 & 16 years.
Showed them the videos first to see what they thought of them - youngest said she loved them - eldest said "Doubt if I would use it much".
When I said I had them in my car, they both soon made quick work of unpacking them.
They both learnt very quickly and were soon whizzing around on them.
So I had bought the right thing - which made them and me very happy.
