First time posting, so let me know if I'm doing anything wrong!
Today I have for sale my father's M15 with number pad, this board has been cleaned and tested. We have found zero issues with it. EXCEPT that the number pad has a crack on the bottom. The number pad is a preproduction model and has the stickers to show it. The keyboard functions fully and is ready to go to a new home. Along with that there is a slightly less harder to find M5-2, M5 with trackball) and that also has been fully cleaned and tested. But keep in mind the trackball does not work with anything above windows xp, because the drivers just do not exist for it. I have posted these on reddit but did not get any hits on these two. If you have any additional questions/offers let me know. And if more pictures, want to see it in a video call, etc. That can be arranged as well!
M15: $1650 Shipped CONUS OBO
M5-2: $250 Shipped CONUS OBO
