I use Resmed F30i, and recently changed the face part (not the frame). It really seems to be substandard compared to what I got when I bought my setup (internal valve flaps don't move like original, seal isn'tas good, "feel" is different...). The new one was bought online, and had a good price.

Anyone have experience with ""knockoff" Resmed products?
