Very pleased!  But the bad news is you have to take your entire dryer apart to install this tiny part. The good news is it's a very simple fix and you should try this first if you've had a large accumulation of lint and your dryer stops heating. I fixed my dryer in one afternoon for under $20! It's 12 yrs old and I'm very happy  that I can keep it going. Once you realize these parts are so easy to replace there are a few other repairs you can do (such as replacing the heat coil, or moisture sensors) before replacing with  a new machine.
