Generally I'm a big fan of iFixit and the tear down guides but this one is seriously lacking. Firstly, there is no indication of where to get replacement parts. I understand that Pebble do not have a solution to supply repair parts to the market meaning that a tear down is a pointless exercise as the item is junk if it's broken. There also aren't any third party suppliers that I can see. The next problem with this one is that during disassembly the button ribbon cable was torn and it seems no mention was made that it is now unusable. More photos are required and a big warning that the cable will tear easily when pulling it away from the adhesive.
Otherwise keep up the good work ifixit
