My son & I just started a month ago using a treadmill. At first it was boring, but I found if I watch a TV show or a DVD that's about the same time as my workout it goes faster & it's not as boring. By the time the shows over I'm done & I'm not watching the clock.
We have extra features on ours we never use except the fan - that we love. Plain & simple is better. We don't use the Ipod or all the fancy workouts. The IFit is pretty cool though. The space saver we thought would be useful, but found once a treadmill is put together it's really too big to move around much & won't fit thru door ways.
