I find it perfectly fine and acceptable for long periods of time, I think the original keyboard is quite good mechanically (springed keys with conductive rubber feet onto pcb pads), the ergonomics of the breadbin (I have an ultimate64 and a few real ones) is not my cup of tea, it ends up hurting my wrists after longer sessions, no such problem at all on the C64c models.
