Nice and easy
Screw drivers weren't really necessary in this kit but the other tools and glue made this a simple replacement. Just note that I did have to add a scrap piece of carton against the back of the pcb in one ear bud as the the left over adhesive + glue wasn't giving enough pressure to keep the board pressed against the battery

Nice lots of extra stuff.
So far the batteries are working and charged to 100% Will see how they survive after a year

Highly recommend.
Phenomenal kit. Batteries are better than the original. They charge fast and hold a charge great.

Good Kit. Good result.
The kit is fine. Baterias are very good. Tweeters are not strong enough, maybe could be better. Glue is fine. Final result is what I was looking for.
