I bought a Space Saving Keyboard from dcozart. It was as he described: working, clean, and with a couple of issues. I bolt modded it and repaired it and I'm typing on it now.
He describes this one being in "great condition ... used daily" which is a much more positive description than the one I bought. It sounds like a turnkey unit.
To whoever buys this. I have a set of 1391401 keys just gathering dust, make an offer. Why be part of that hipster Otaku fad when you could be legendary?
