Just finished using this kit - some notes for all:
1 - Tools - I did NOT use the Phillips tool with the kit after reading several comments about stripping the incredibly small screws, I used the smallest standard screwdriver I had in a jeweller set that I already have. Note that these 2 screws are VERY small, and can tend to drop back into the body when re-assemembling. A set of tweezers is very helpful, both with this and the grounding clip. Shaking out the screw driver on the top had to be done several times, along with resetting the ground clip - this really seems to be the hardest part.
2 - PLEASE look at the video from HighTechDad re: the grounding clip!!! It readily points out how this part can (and will) pop off when removing the battery connector. Watch the video FIRST to see how the clip is oriented, and tweezers are very good to use here.
I had a magnifying glass handy, just to get a good look at the connector after getting it apart.
