Sunny Health and Fitness SF-T7515 Treadmill vs XTERRA Fitness TR6.6 Folding Treadmill

The Sunny Health and Fitness SF-T7515 Treadmill is a relatively good Treadmill for people that are willing to spend around $390. The XTERRA Fitness TR6.6 Folding Treadmill, by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.

In both cases, however, we recommend that you take look at some other options at the $390 and $830 budget ranges; in all likelihood you'll find some better alternatives.
