I have been using this model since the year 2000 or 2001 (I cannot remember). It has been faithful until today 30th April 2007. If I had to buy it again I would.
The only problem I had was the BVRP software that came with it; not very stable.
I have been sending and receiving fax documents with speeds up to 36 kb/s.
The price was higher than other ordinary modems in that time, but it was worth it!
