So this isn't as bad a switch as I thought it would be. Sure, it is scratchy as can be, but I think they will smooth out over time with use. The keycaps are shallow and the travel is pretty short and these are linear, but I'm going to try changing the keycaps to regular height and see what happens.
For $26 and change, these are a pretty good deal if you need a external keypad that isn't some crappy rubberdome.
