I thought this was going to take all day. Nowhere has switches in stock, and I have a board with really good switches that I'm not using. I got this SS-02 solder sucker and it's supposed to be the best. I was hopeful with a sensible measure of skepticism. I mean, how good can it really be?
Turns out; "very". It's so much better than the plastic tip suckers I've used before. Getting a seal over a joint is effortless, and even if you can't get a full seal it does a great job of pulling solder out. I was only (!) going to desolder 46 switches (I have 12 Zealios left for thumb row, escape and backspace) but ended up doing the whole board as I was having so much fun with it.
The only downside is you need some good pointy tweezers to pull cold solder out of the tip occasionally, but that's quite a satisfying task in itself as it comes out like a little silver scab.
