Not a company that can be accused of mass producing 'me-too' climbing gear, DMM seems to constantly strive to push the envelope forward with items of climbing gear that offer genuine utility rather than faddish design.
Whilst products like the mamba caused a genuine stir, items like the humble screwgate offer less excitement factor.
However, DMM seem to have struck gold with the Sentinel screwgate. It is a proper belay screwgate with an interesting shape which tends to keep it in the upright position, the narrow lower end of the krab sits perfectly in a harness belay loop whilst the flared out top end is perfect partnered with the DMM Bug or even a humble munter hitch if you are craving old school climbing adventure.
The krab is of an I-beam construction and has that lush, almost tactile anodising DMM seem to have perfected. I love the fact that this krab isn't a huge lump of metal but rather pretty diminutive in size whilst still offering full belay krab spec.
The screwgate is flawlessly made with no sharp edges and nice knurling to the lock, it stick well in the locked and unlocked position.
All in all a pretty perfect iteration of the belay krab and a sublime partner to the Bug (see my review of that).
