Overall, a neat piece of gear, but I don't use one myself. Usable
enough. ATA of two FXS ports for under 100USD was a great deal at the
time this came out. Feature set is full enough for average use
pattern. Price/feature was very good 6 months ago, and is still above
average. However, reliability is not stellar, and no extended warranty
is available. For most 2-line office users who can accept a small
amount of risk that their hardware will croak, this is a fine ATA.
