Very practical, stable tub use for example for older people. It is easily adjustable, so dasss he is individually adaptable to the bathtub. Unfortunately, the only fasteners of plastic, so that a holder is not available after 6 months dissolved / broken out of the turn. Fortunately, this is' not done according to simultaneous usage. Now he can no longer be used. Therefore, instead of 4 only 2 stars. Pity!
