Product review (4 stars): Good bundle, great price, eaay to install.
Brilliant! My drier died mysteriously right before I was leaving on vacation, so for the 35$ this kit cost, I figured I'd gamble on it being one of the included parts.

Took me about 20 minutes to install all three components and the dryer started working again. In my case the heating element had failed, but the thermal fuse is the highest probability part for early failure. If your dryer is new-ish (say 3 years), I'd say just try changing the fuse, but if it's over 5 years old, I'd recommend swapping out all three components.
