Have ordered the ball as a replacement for my old ball, since this unfortunately had a hole. Until extent very pleased with the Togu, but the first few days were a little getting used to. Unlike other balls of Togu needs due to the fairly rigid ABS material a few days' warm-up time ". Say first inflate a bit, wait a few hours, then inflate completely, wait 24 hours, then again a little re-inflation. But now he has probably reached its final size and will remain beautiful in form. Overall, I am very satisfied, but the somewhat cumbersome inflation elongation time is a star deduction.
