DMM Revolver for rescue?

They seem like a really good alternative to a normal biner or those
absolutely useless petzl 'ultralegere' pulleys when you want a couple
just in case. Running around glaciers and whatnot- i need a few biners
lying around anyways. Could I use these for rescue situations? If
they'd double as a normal biner and a biner/pulley, they'd be worth a
few extra bucks to me.

I didn't see any specs on working load, although I'd imagine the worst
that could happen is the pulley stop functioning, and just end up with
a normal 11mm radius surface.

Any experience/thoughts?

Not sure what the use would be:
- the diameter of the pulley is very small, so it's no use to haul anything (anyone who has tried
a 5" pulley vs a 1" one to haul a pig knows the difference).
- when climbing and taking falls you _want_ some dissipation by rope drag, otherwise being belayed
by a lightweight dwarf would be all but impossible.
- It might be some use on those long trad pitches with gear everywhere and tons of rope drag in
the end... But then you will end up with gear being pulled in directioned you did not intend when
you placed it (a long sling is safer in that respect or, better, a double rope well clipped)

Also the load specs are pretty low for this type of device so would probably
not be first choice in rescure work.
