Keeping up with all the latest product changes can be difficult sometimes…. When my husband and I looked for a treadmill we went to the brand names first. After not being satisfied with the lack of knowledge we found from the specialty dealer in our home town of Phoenix, we started becoming experts ourselves. After a couple of weeks of doing our due diligence we decided the Xterra 6.6 was the one! Great product with great features and Fantastic price!
