Very happy with my NordicTrack treadmill! Very sturdy - my favorite feature is the way that the bottom lifts up and down for moving. The mechansim is very smooth, which makes it easy to put down without worrying about it dropping on me. Printed instructions were brief but there was helpful videos and more info that they referred to online that made it more manageable.
I was given a discount on this product in exchange for an honest and unbiased review, which this is!
