I didn't even disassemble (unscrew) my pebble. Just applied a drop of mineral oil to the button and it did help a lot! Thanks!
Hi Emma, Is it fine to use the spray version of wd40 if not what is the difference?

I'm finding the issue with my new Pebble isn't so much that the buttons don't work. It's that they are unreliable because if you don't press near dead center on the button, it doesn't actuate enough to press the microswitch. I feel like this is a design flaw, but maybe this guide will help. On the plus side, at least they built it where it's easy to take apart.
