All right! It just came! I'll let you know how it goes. This guy's keyboards are usually in at least middling shape, but are often in need of some work. I understand on many acer designs it's a matter of opening the case and essentially hanging the membrane out the window to dry and you're good to go, so I have high hopes. I'll be back in an hour.
EDIT: it's here and I did have to do a bit of maintenance on it. Percussive maintenance. Tell me if I'm way off here, but I feel like oftentimes if you have a weird switch you just smash it really hard a few times and it starts working.
The zero key was stuck down so I ripped it off and just smashed the switch a bunch of times for about 5 minutes straight and it's fine now.
The board's a little bit dirty, and the inside is hella corroded, but it's functional and it's not disgusting. Exactly what I have come to expect from this seller. Solid G rating gear. He also mailed it in a shop vac box, which is also not that weird. I don't know where the guy finds the boxes but they're always weird and different. I got one keyboard from him in a box from The Game of Life iirc.
Feels good. I mentioned in the Alps appreciation thread that it feels like low rent Matias, basically. Great $15 board that I'm going to shove in my closet and never use dear god why am I here.
