Had to keep the phone going until the iPhone 6 hits next month, and my kids are going to want the hand down. So the parts are cheap enough and I'm sure with the video I could handle it.
There repair went fine, need a strong pair of reading glasses.
The repairs aren't to difficult, you do need to have patience and attention to detail. A screw bin is very useful, I used the box the parts came in, the narrow slots where the tools where helped organize the fasteners. I believe with some minor modification, that the box design could be improved to really complete the kit. Now if you could include a better set of eyes ;-) The kit itself and the videos are well done and quality replacement parts.
