Good, but not my favorite.
I bought this along with my petzl attache because they were both similar and seemed perfect for belaying. This is a smooth biner and infinitely better than rental equipment, but the petzl is just better. I would buy this biner again if I needed a new belay biner and my petzl wasn't available, but I have a few gripes. The lock takes twice as many spins to close completely. The gate doesn't open as easily as my petzl, and since it is slightly smaller, it is more difficult to clip and unclip. The Element is very smooth and looks badass in the burgundy color but I'd rather spend the extra $5 and buy my petzl again. However, if you can't spare the $5 and are considering this biner, go for it.
