Used it for a full day of belaying on a via ferrata and my hands never slipped once, the grip is genuinely excellent even when the rope got a bit damp. At 9.8mm it's light enough to carry all day but still feels solid and durable.
The 9.8mm diameter feels light on the harness without skimping on grip, which mattered on the wet sections of the route. Only gripe is that it fuzzed a bit near the ends after a few weeks of regular belaying.
Took this on a via ferrata trip and the 9.8mm diameter feels light on the harness without feeling sketchy on the belay. Grip is solid even with gloves on, though it fuzzed a little faster than I hoped near the ends.
