Get this only if you're replacing your shell

Involvement:General (knows how to use it) - Ownership:more than 1 month

-Very cheap

-It replaces your dead microphone and/or you dead wifi antenna

-Look really similar to the original ones

-The mic is a little bigger than the original one *the rubber part), so it doesn't fit properly

-Comes with the wifi antenna, which I bet is useless to most people, as most people need only the microphone replaced.

-You might wreck you system while installing these, making them completely useless

It's to much of a hassle replacing these. If you're planning to replace your shell, and your microphone doesn't work, then sure you should buy it. Otherwise it's just not worth it. There are maybe 3 games where you need the mic.

I don't even know why you'd need to replace the antenna to begin with, so I'll just ignore it.

If you don't get any signals, then you might need it I suppose.

Here's a good guide I'd suggest you to use:

Awesome price, I just wish they'd sell them separately. The antenna is really useless to me.

Get it only if you're replacing the whole shell.
