I have it on my LG Watch Style and MK Access Grayson (but I believe it's never coming to my 1st gen Huawei Watch). It seems fine to me, although not a gigantic leap forward. I honestly don't care about the fitness features of a watch, so swiping left to see my steps is meh. Long-pressing to change watchfaces makes more sense to me than swiping left or right, though.
