I followed the instructions and replaced my HD with and SSD - well worth it.
However, several glitches along the way:
1. The TR9 screwdriver I purchased from iFixit sucks. The handle turns but the shaft doesn't. The screws holding the original HD to the tray were so tight, I had to go to Geek Squad to have them removed.
2. It wasn't clear what the power supply clip held in place. I managed to get it back in, but I'm not sure it is holding anything.
3. It was not clear if the tape holding the SATA cable connector to the original HD was needed for the new SSD (It wasn't). I ripped it while taking it off.
4. The DC-In connector to the logic board would not come out using fingers - not much room to get fingers in. Had to pry it off using a flat head screwdriver.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
