Works perfectly in WF-1000XM3 earbuds, but no instructions included
Worked perfectly for my WF-100XM3 earbuds. Note: there are no instructions, so find a how-to video on YouTube.

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

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

I think this kit was old stock that has been sitting for a while
The adhesive was all dried up so I’m assuming this was sitting on a shelf for a while. I swapped out the batteries with no issues but the earbuds are dead. I think the batteries are really old as well?

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.

Muy buen paquete. Todo incluido
Las baterías son iguales a las que vienen de fábrica. Las cambié sin ningún problema y funcionan de maravilla. En el paquete viene todo incluido para el proceso de cambio, por lo que no necesite ninguna otra herramienta ni sellador. Lo que si es muy recomendable para hacer un trabajo limpio es conseguir una pistola de calor para aflojar previamente el pegamento de los audífonos.
