Product review (4 stars): Great deal
If you've tried to price individual parts for overhauling an electric dryer, it can add up pretty quickly.  This kit is nice for several reasons:
1) It's got all the main parts that are likely to need replacement due to wear after a few years of constant dryer use.
2) It's got official parts and needed adhesives and lubes, not knockoffs of unknown quality.
3) It's a good price!
4) It has some installation instructions, but they tend to be faint photocopies of photocopies, and sometimes for a related model/part rather than for exactly what's in the package.  The Internet can usually solve this problem, though, especially with all the DIY videos posted online.
