I'm not sure. I can see how it might help the sensitivity in adjusting the brightness once it's on. But it's unclear to me how it would change the amount of turning to go from off to on.
That's the big deal for me. Even with two hands, it's a couple of cranks. So it takes almost two seconds for me to get light out of the Gatlight with two hands versus a quarter second one handed with the PD.
Not a big deal at the bedside. But crucial when I'm trying to see if that jingling sound is another dog running towards me in the park at night while holding on to my straining dog's leash with one hand.
