I bought this bellicon several months ago. But only recently started using it. My chiropractor encouraged me and my 73-year-old mother to use it. We've been using it about 5 times a week now for almost 2 months. I've noticed a difference in my energy level.
The bellicon is well built and perfect for a New York City apartment (2nd Floor). It's very quiet, and thus no problem with the neighbors below us.
