  • You want a touchscreen. More expensive treadmills come with touchscreens and web browsing. You can get a Matrix treadmill if you truly want all the bells and whistles. But the T616 gets the job done at a more manageable price.
  • You need a longer warranty. Many treadmills offer lifetime warranties on at least the motor and frame. With the T616, that warranty only lasts for 10 years.
  • You'd like a free app trial with your purchase. Some treadmills give you a free 1-year membership to a fitness app, usually iFit, with your purchase. You don't get that bonus with the T616. But you're always free to download an app on your own to sync with your new device.

Key Nautilus T616 Specs

Reasons to buy Nautilus T616?

  • You like being able to store your treadmill. The SoftDrop folding system allows you to effortlessly fold and store the machine. It's great if you have limited space in your home and need to keep your treadmill out of the way most of the time.

Reasons to avoid Nautilus T616?

  • You're a bit heavier. The Nautilus T616 can support weights of up to 300 pounds. Considering the frame and motor, it should be capable of supporting a lot more.
  • You plan on sprinting a lot. Some reviewers have noted how the T616 doesn't hold up as well under strenuous conditions for a prolonged period of time. It's preferable for walking or moderate jogging. But it may not hold up as well if you push it to the max every single time.
