Hey Vette,
I have had one 2 years or so, and I have had no problems,
Its basically a twinhan, I belive I read there are getting few and
far between to find. I bought myself a extra one and put it up, in case mine goes
down, and it will work with MT and prog. for sure, just during setup, reconize it as a twinhan compatiability, and it should work just fine.
