The thicker three-ply belt is more durable than those on cheap treadmills, and built to last. The T618 has a Powerful 3.5 HP motor which means it won’t be straining to keep up with you (Straining motors burn out quicker).

Nautilus the company has been around for almost half a century. This is one of our top models in this price range.
