It's a few years old, but with it's original $2500 price tag, this commercial-grade treadmill has a lot of things you won't find in a newer entry-level priced treadmill.
-3% to 15% incline, up to 12 miles per hour, 350 pound max weight, 22"x60" running surface, EKG grip heartrate monitor, 2 speed cooling fan, port for phone with 2 speakers, 7" LCD display, and lifetime frame and motor warranty.
It still works like new, the only time I thought I had a problem with it was because my toddler took and hid the magnetic safety kill switch.
