I bought the balance board, because my physical therapist told me to something derartigem. Since I've torn through soccer games already 5 times the tapes, I was to get such a board to stabilize the foot and the bands to buy. The base is in this case relatively heavily used, but in a good way. You can tell right, as the foot has to work to compensate for the shake. I use the board especially in the morning and evening while brushing your teeth. Of course it's not easy to keep up on the board, but you get used to it. I quickly managed a long time to keep the balance there, and I must add that my father had thus carried out problems. So I think that the difficulty for the balance means is classified. The price is right and the delivery was as described. So in conclusion I can only recommend the product.
