Anyone ever used a Camp Andry Pulley?

These things are dirt cheap but I can't find a single review online. There's an old MP thread about pulley efficiency but the images don't seem to be working.

Has anyone used on of these pulleys? Do they seem functional for crevasse rescue? I'm looking to pick up a couple of extras for C on Z setups. Already covered for the main anchor/progress capture pulley so they don't need to be prussik minding.

$6 each! Any thoughts will be appreciated.

I wouldn't get anything without bearings. Dmm and petzl charge top dollar and provide stuff that last .

Looks about as good as the plastic pulleys they sell that you can put on a carabiner. rei.com/product/799043/petz…

I had a different camp pulley once and it was junk, the part that spins locked up when more than a 100lbs was applied due to the points the carabiner clips into squeezing the pulley.

I have a few of them. They are made of steel, so they are heavier for their size. It’s just a plastic sheave on a thin, friction-bushing axle. No bearing or real bushing of any type. They are as cheap as it gets. I recall the efficiency being a really low, like 80-85% or so.

They are basically like one of these, although possibly marginally more efficient:
