This is a great multi-use belay device. The toothed side is perfect for belaying a heavier climber, or for a single-rope rappel; the device is great for belaying a lead climber, or a top-roper and can be used to belay off an anchor. After 2 years of belaying with this device, the teeth are definitely showing signs of wear, but due to the triangular shape it is still sufficient for a controlled belay or rappel. If you're only going to buy one belay device this one is pretty great!
