I had an older one that doesn't bear leg weight from another brand, which required you to tighten the robe, which makes it less flexible. This one works better. and the customer service from this vendor is really great. We had a really great correspondence on my experience with it.
Very interesting design, I could put it on my feet, feels just like a swing. The product itself is very solid. Now I place it under my desk, when I had to extend my work hour till late, this thing makes me keep on going! It kind of give me energy when I was out of inspiration, or kind of stress out. Fun to swing around when boring, I really like it, would recommend it to my co-workers and friends.
Really cool concept. The kids liked it. It slipped under the weight of my adult feet though.
