After a ligament tear ankle, I was looking for a way to stabilize the ankle a little and to train your legs. After some research I stayed at this balance board hanging, also because of the low price compared to other products. The gyroscope is made entirely of hard plastic, that is, which is not compressed and the contact surface of the gyro and one Daduchus has a lower support surface. Which of course also increases the level of difficulty. With socks on the roundabout to train makes me due to the rough surface little difficulty, but Barefoot has something more support. The enclosed mat should use it, otherwise the gyroscope on the carpet is quite slippery. As a beginner like me, you still do quite difficult to climb to the top. But if you hold a hand on a piece of furniture and with one foot initially rises exactly in the middle of the roundabout, and then follow suit the other foot, that's pretty good. Thus, the ankle is not kinked. With the product, I am very satisfied from the quality, and you can tell pretty quickly the effective action of the device. I would buy it again at any time.
