The summer camp where I worked bought a bunch of these last summer to help replace our aging, worn belay devices. These are almost completely identical to the Black Diamond ATCs in appearance, but the quality on these is much worse. They belay fine, but after very little use the plastic coating on the wire wears away, leaving the wire exposed where it can wear on the rope. Some of the ones we had lasted a week or two, while others would go bad after only a few days of use. We were forced to switch back to our old belay devices halfway through the summer because all of these had been retired.

I would not recommend that anyone buy these despite their low price because the coating on the wire will wear off quickly and you will have to buy a new belay device. Spend a few more dollars and get a high-quality Black Diamond ATC that will last years instead.
