Query: Balance Problems

I don't really care for this product. I feel it should have a much larger platform to stand on for the exercise it is designed to do. It is smaller than I imagined and hard to stay on it as you try twisting. I wish I had known how small it was before I bought it. I am not large, wear only a size 7 shoe in fact and although I do this barefoot, I do not feel it is comfortable enough to stand on or very safe either. It is easier if you stand by a wall or use something to hold onto as you twist as it is easy to fall off of it. Holding onto something helps you stay on it. Balance can be a big issue for this product. It is not a recommendation of mine.
