Summary: I purchased this Bosu to help keep my dog's rear legs strong to support her hips affected by hip dysplasia. This was the best price I could find, and the product is perfect for her exercises. Very pleased. I can't give it 5 stars because in general I believe these are overpriced, but this was a good value. This size supports my dog who is about 55 pounds, and could be suitable for a larger dog as well.
Summary: I worked with the Bosu Professional edition with my physio and I believe this is meant for less strenuous/personal use. I am very satisfied with the product so far as I don't see major difference between the two. The only thing missing the solid base at the bottom that would perhaps be needed if it is going to be used a large number of people at the gym.
