The only reason why this product has ever earned star is that it is appealing from the optical ago. Only there are some features that are simply not convincing. The size is not the sense of conventional opinion. The step is much too high positioned, or the area of the upper body is not sufficient. In addition, a large bulge in the abdominal and back area results in humans, where the product is suitable at all. I hope that the restitution can take place without further complications and recommend this product only limited to the purchase. Either 2 sizes larger or find a producer who produces in standardized sizes.
