No issues, works exactly as designed to ensure the carabiner doesn't turn while belaying, which was a problem I'd had with other carabiners during lead climbing. The screwgate turns easily and smoothly. If I had one 'upgrade' suggestion for the Black Diamond product development team, it would be add a visual indicator (such as a red stripe) that shows when the screwgate hasn't been secured and the gate isn't locked. It's been excellent though.
I was using the older model gridlock screw gate with the integrated gate mechanism. I had to fiddle with it to properly attach it to my belay loop and Black Diamond pilot. Same experience removing the older device from my belay loop. I am happy with the new design and independent wire to isolate the belay loop. No more fussing!
