Mine just arrived, and are completely unusable. When I put them on, the switch simply won't spring back, and the spacebar will be continuously pressed down. I'm not sure if this is due to the obvious warping as can be seen in this pic.

Either way, I'm pretty unhappy with this, especially considering how expensive they were.
Linusarinboth doesn't work?Or try another keybord? Or try to install another spacebar?
It is just a keycap. It seems to have nothing to do with the spring.
