I love the simplicity yet concise feel of your guide. There are just enough steps to keep the reader motivated to go through with the repair, too many steps and your average reader would back off.

Your instructions were very clear and straight to the point and I appreciate the fact that you did not use any complex words to describe the steps so as to cater to an audience with little technical knowledge.

The photos were awesome as most of them had both your hands in them which gave a first person view perspective. On top of that, they were clear; without any motion blur . The pictures were also organized in a flip book style which further gives a sense of orientation to the reader. Nice use of markups on the pictures too!

Great work and well done.
