I've heard good things, which led me to buy them, but my personal experience wasn't as good. This was in the front of an '09 Civic. The pads would squeak for a few miles every morning. Plus, I felt that the pads were a little grabby until they warmed up a little bit.
After a few months, I went back and cleaned the bracket and slide pins, and put more anti seize on the pad ears, but it kept squeaking. I've lived with it for a couple years now, but I think I'll swap them out this summer (with plenty of pad material left).
This could be user error though, I lubed the back of the pad, where I've read some posts where the Thermoquiets have an "IMI" Integrated Molded Insulator backing that is suppose to be installed dry.
