Great treadmill. Was very impressed with not only the build quality but the quality of the operating system that this treadmill uses. It can do literally anything you want/need. In terms of running deck, this really felt cushioned and easy on my joints. I connected the heart rate monitor to it and within seconds, it was all working and ready to go. Loads of fun to be had with the maps you can select to make your workouts a bit more exciting. It's not a cheap treadmill but you definitely get what you pay for - a real bit of quality.
