I love mine. The only "bad" thing I can think of is that at first you have to go alot ( or at least me, my husband and our children did) until you get everything where it should be. We started at once a week and now only go once every 6 weeks. I have not had as aches and pains as I did have, my sinus troubles are soooooo much better, I sleep better and I just plain feel good.
