I ordered one. Keycaps pass Acetone test. One of the internal stabilizers for the cable strain relief was broken, but the keyboard was otherwise good. I find it interesting that they put a keyboard condom on over the extremely wear-resistant PBT. Keycaps look untouched.
I'm not having any problems with off center hits or anything. It's rather nice to type on, if you keep it light and I don't bottom out. The actuation point is pretty close to the top of the keytravel. I am still deciding whether to convert to to Dvorak.
Overall, an excellent purchase. I will use it every time I travel.
Oh, anyone want the cover? It's in good shape, though none of the adhesive is left (It's all stuck to my keyboard)
