Theracane didn't work well for me like the Beastie did. Your mileage may vary.

Since using the Beastie, my back has never gotten as tight as it was at its peak, but I still need to use it at least every other day. It's pretty fast though: about 2 - 5 minutes gives me some real improvement.

It still hasn't been long since I started, but so far so good.
