Significantly different from the 100i
I loved the AMT100i, and I would switch gyms to find a place that had it available.
my gym just upgraded to the 835 and it's lost all the things I loved about the 100i.
you now have to make manual adjustments to the height of each step, and it seems like I'm constantly having to switch between height settings and can't find a comfortable rhythm. I'm currently searching for a way to get back on a 100i, because the 835 is no good.
