Actually a great ball, got it bought for my Jack Russel. The ball maximum by holding a month, I have therefore taken into account. Inflated ball, went to a meadow, rausgeholt ball and determined that the ball has clearly lost air. Well, nem dog that is probably not matter as long as it rolls. Since he was not leaking, I guess times on valve. Sometime is then also the valve slips, had with the needle until the valve back to the opening draw To be able to inflate it again ... As far but still acceptable. Has two months persevered until the ball was gone ... is therefore very robust, but that the ball loses air, is an absurdity.
