They're wonderful.

I've got both the travel version and the longer "home" version...longer version is great for back/shoulders and is also easier to use on legs...more flex, more leverage for those tough knots...

My wife doesn't like them...says that they hurt her skin...?!?

FYI...I was carrying-on the travel version to combat DVT on a flight and almost had it confiscated as a "billy club"
