Just started on rollers a couple of days ago. First 2 minutes, I thought this is going to be the death of me, but as everyone notes, it gets considerably easier. 10 min on day 1, 15 min on day 2, and by day 3 I was bored of staring at the wall, so I set it up by the tv (can't operate the remote yet!). Still not comfortable enough to ride without chairs on either side. Hopefully I can ditch the props soon.

It seems to be easier and smoother when I use my hips to steer rather than my arms. Also, I put a few layers of tape (short strips, maybe 4" long) near the edges of the front roller; it lets me know when I'm about to roll off - kind of like highway shoulders that are intentionally rough to alert you that you're off the road.
