I try to use this treadmill everyday. It is awesome. Much more comfortable than walking outdoors. It keeps time and distance for you, and so much more. So many features, it may take awhile to figure out, but they are great! Buy this treadmill, you won't be disappointed! It is very heavy, and does take up space even though it folds up, and it takes awhile to put together.
Generally I'm very pleased with NordicTrack C2255 Treadmill.I seem to use it mostly for walking or jogging and not for hardcore running.
