This belt is a replica of the Bison Designs 30mm T-Lock belt. The clasp is identical. On the other hand, the straps next to the belt loops are much more flexible and twist quickly. For that reason alone I would avoid this belt and prefer the Bison Designs belt. About the buckle. The only complaint about this buckle design, whether on this belt or the original Bison Designs belt, is that it will inevitably break. The most common failure mode I've found is when someone steps on the buckle while it's on the ground and not latched. After losing two straps this way, I got into the habit of snapping them in place every time I took the strap off. Eventually the plastic will fatigue and crack on its own. It doesn't bother me that much as it will last for many years. And since I haven't found a belt that compares to the Bison Designs belt, I'll keep using it until I find a better one.
