The Proform Performance 600 treadmill is low price entry level unit that does have some nice features, but does lack a certain level of durability and usability.

The LED display is very hard to read as the console positioning is very awkward. Also, the button placement makes changing settings during a workout very difficult, creating an unwanted distraction. The ipod+nike compatibility was a nice add-on but we found the features were poorly integrated into the workout. The air cushioning is a great idea, but on this unit the cushions would bottom out during fast pace workouts causing an interruption to stride and pace.

The Proform Performance 600 is a low quality entry level treadmill that boasts a lot of features that are either poorly integrated or poorly designed. The overall package offers poor value for money and I would not recommend this treadmill. There are other treadmills of much higher quality from different manufacturers for the same price.
