Well, I wonder If they plugged it in right, or did thay plug it in
at all? ;-)

I don't know of PC Magazine tests, but I know this:

I am using a TB2500 for an overseas connection 1/3 the way around
the globe. The line is VERY noisy, it has my TB running at "only"
350-700 Bytes/sec. I can get a connection almost every time
and hardly ever loose it. I have tried several other connections,
including 1200,2400 (w and w/o MNP) and 9600 V.32, I have not been
able to keep anything other than a TB2500 with PEP on the line
for more than 30 seconds (actually, there was this one 300 baud
modem...). PEP splits the line up to 512 different bands, and
uses the clean ones. This makes it much more tolerant to line noise
than normal modems.

If TB2500 aren't good enough to hold the lines on noisy connections,
then I would recommend against modems in general, since I haven't seen
anything BETTER.
