I stripped some thinner wire than telephone wire the first
time I used it, multiple wires at a time just for fun. Seemed
to work fine. I am looking for a video that demonstrates the
use of the knob that apparently tightens it down for very
thin wire.

There have been lots of times when I needed to strip several
very thin stranded wires the same length, a major hassle.

I am sure it has some limitations, but completely outweighed
by what it can do.

Definitely would avoid the Chinese knockoffs, especially
considering how cheap it is anyway.
