I have the BOSU Balance Trainer Pro met during a physical therapy and was excited about the possibilities for abdominal training. The device is very versatile, as well as the largest such machine on the market and appears to be quite robust. The manufacturer advertises with high quality standards by manufacturing at the company headquarters (Ashland / Ohio) rather than abroad. Compared with the somewhat smaller German competitor "TOGU Jumper" reached the BOSU trainer in my opinion not quite the perfection in the workmanship of the German unit. In addition, the surface is much smoother with the BOSU and can be slippery when entering with stockings. For the TOGU on the surface is rougher and therefore more difficult to clean and dry. During the presentation on the Internet, such as on Facebook or YouTube, however, the American BOSU Balance Trainer has the nose clear front - especially on YouTube various ways of training will be presented in a very large number of videos. The pertinent to the BOSU trainer pump makes a somewhat primitive impression dissolves during inflation even slightly from the valve, but it is included in the price. In addition, the BOSU trainer transpires in the first few weeks slightly from (smells slightly inflatable or plastic ball), while the German TOGU Jumper is almost odorless even in the new state The price is currently with 129-150 euros - depending on the provider - at a fairly high level, with the same device in the United States for only 109 dollars offer. Overall, I am using the BOSU Balance Trainer Pro but very satisfied. For the same reason it is well used by most physical therapists and gyms.
