Well, I have an HDS Rotary, which is the only other tail rotary control I can think of right now. Of course, I like it a lot. It is durable, reliable, versatile, bright enough and beautiful (the high CRI variety). No issues using the dial, either overhand turning it with the thumb and forefinger, or underhand, holding it with the pinky/ring finger and turning the light with the thumb and forefinger.
I started to get interested in this light too, until I saw the low of 30 (claimed) lumens. No point in a dial adjustable light for me if it does not go down to at least 1 lumen, preferably < 0.1 lumens. Nice review, though, told me everything I needed to know.
