Familiarity: I've used it several times
I got this thinking it would be my belay biner with an ATC Guide. It comes up short in this department.
Compared to the Petzl Attache 3D the Vapor is not as smooth at rope pulling (especially belaying off of the anchor) or rappelling. Also, the Vapor weighs a tiny bit more than the Attache 3D, and while it has the Magnetron feature, I'm not a huge fan of this locking mechanism. If you want to lock it or unlock it with one hand, you pretty much have to have the spine in the palm of your hand. There are times when this is inconvenient, and annoying, given that most lockers can be operated in multiple orientations with one hand.
Luckily I got mine with a gift card for cheap or it would be going back. It has been relegated to use with my PAS, where I'm almost always clipping it with the spine in my palm. Also, the large opening is good for getting around a lot of tat.
Still, for the price I cannot recommend this biner.
