A great looking treadmill, but that's where looks can be deceiving!

The Proform 520 ZN is a great treadmill if you're trying to make guests think you exercise or if you like really expensive coat hangers. At $599, it's actually a good value. Unfortunately, a good value at this price doesn't translate to a good treadmill. If you want a good quality machine, you're going to have to pay more than $600 for it.

The walking area is a good size. The belt measures in at 20" x 55". This is a bit shorter than the standard 20" x 60" walking belt, but you can find several models that are more expensive than this one that don't offer a walking surface this accommodating.

The motor in this machine is quite weak. Not too many treadmills have less power producing capabilities than this one does. Still, it's not that bad within its price range. It can reach speeds of up to 10 mph. We wouldn't recommend using this model for running, however, as it will probably damage the structure and drive system. Cheaper models like this one should only be used for light walking.

The cushioning system is okay. AirStride Max cushioning is used to reduce the impact that running has on your joints and back. In this price range, you're not going to find much better, but overall more forgiving running surfaces are readily available.

The projected reliability of this treadmill is bad. Other machines that cost as little as this may have a shorter life expectancy, but if you're willing to pay a few hundred extra dollars, you can get a major jump in life expectancy. There aren't many models that use lower quality parts than those used in this one.

This is one of the loudest treadmills we reviewed. Even among machines in its price, it is louder than most. If quiet operation is important to you, stay away from this model.

The warranty on the Proform 520 ZN is sad. Parts and labor are covered for 1 year, the motor is covered for 25 years, and the frame is covered for life. This kind of coverage is common for treadmills that are this inexpensive.
