All in all the shell is really good, but there's a few things you should know before you buy:
1) The shell-swap itself is a delicate job to do that demands high attention--it's very easy to misplace where you got a **** from if you don't actively note where they come from. Also, depending on the age/condition of your wii, the interior plastics which will stay with the Wii internals can be very brittle, so proceed with care. There aren't a lot of tutorials online that actively show you where each **** goes at present, so don't expect any hand-holding love from YouTube.
2) The included Sync button is painted to be red instead of being a red plastic. It can look really tacky, so I recommend just using your original sync button assuming it fits the shell you get.
3) The new shell doesn't come with the dust-guard felt that the original wii has, and it doesn't come with an air-intake mesh. If you really want one/both of those, you'll likely need to salvage those out of your old wii during the teardown.
4) The doors to the shell don't fit flush on my wii, but that may be because I learned about the brittle plastics from my 1st point the hard way. It's not a flaw that's unforgivable, but just be aware they may not fit.
All in all, am I glad I swapped the shell? Yes. Would I do it again, no--and that's mostly from the actual stress of the shell-swap process and less about the quality of the parts.
