I tried the haptic sensors for page turns on my Voyage and I also thought they work very well. I'm happy with swiping to turn pages so I never remembered to use them and finally turned them off. I've tried them again at other times, always with the same results.
I do think they're better than physical buttons because I was always accidentally turning pages with them and that doesn't happen with the haptic buttons. If only I had a use for them.
