Bests & Worsts Reviews from Amazon

I've had it for about a month now, and I LOVE IT! Hubby and I are even starting to do sit-ups while on it! I have hip and back pains, and althought when they're really bad, it takes me several minutes to get myself into position on the board. But every time, I'm only on it for 2, maybe 3 minutes, and it's like a miracle! Pain free for days/weeks! I only use it when I'm in pain, because we live in a very small house and have no open area to keep it perminantly. However, I believe if it were out all the time, and I got on it every day, back and hip pain would be a thing of the past. It does take some time to get used to being upside down. I still have to come back up slowly to avoid a head rush. And as far as stability, I'm 230 lbs, so it's deffinatelly stable! And as far as the issue some people have had with the ankle bar's being uncomfortable, I don't have that problem at all. I find it quite comfortable. Seriously, I highly recommend this!! I don't know how I lived without it! Update* 8 years later. It still works flawlessly!
