My Rotary arrived today as well, and I'm very pleased with it. This being my 4th HDS I kinda knew what to expect quality wise, but I was still amazed by how solid the rotating tailcap felt. The anodizing is perfect as well, not a single spec of missing ano as far as I can tell. The LED is dead-on center, and the tint is pure white. It's even whiter than my 140GT, which surprised me.
I was a little worried about the ringy beamshots posted here, but mine doesn't look anything like that. Maybe it's less obvious in person vs. on a picture, I don't know. When shining on a white wall and looking very closely, I detect a VERY subtle difference in brightness towards the outer edge of the spill, which might be called a "ring", but it's much less pronounced than in the pictures I see here. But I don't often shine my HDS lights on walls, and when in "real-world" use, I can't see it at all, even when I'm looking for it.
Needless to say I'm going to EDC the Rotary for the weeks/months to come, and it will be interesting to see how the programming combined with the Rotary UI suits me in daily use. For now, I'm leaving it on default.
