The Mammut Smart is a great alternative to a Gri Gri or other mechanical autolocking belay device. It combines the performance of a full autolocker with the low weight and simplicity of a traditional belay plate. In order to avoid moving parts, the Smart uses the belay karabiner as the cam which locks the rope in the event of a fall. In use this makes it virtually identical to a Gri Gri though lowering can be slightly less smooth.
When a fall happens, the Smart will dynamically brake the rope, even at low levels of force (e.g. lighter climbers or small top-rope falls). The Smart has been updated with improved geometry to give smoother feeding of a lead rope. It is used paired with any HMS carabiner and works with single ropes from 8.7 to 10.5mm diameter - one of the biggest ranges on the market.

This is a great piece of kit. Bought with the intention of adding another layer of safety for climbing with less-experienced climbers (including my girlfriend), combined with the Black Diamond GridLock to prevent cross-loading. The Smart is worth considering as a cheaper alternative to a GriGri. I certainly chose this on price, and haven't been disappointed. There is a knack to using the Smart, but it doesn't take long to get used to. This is simple and clever.
