I consider myself an experienced runner, my last treadmill took was a Sears special and I gave it a beating. It lasted six months of everyday usage. I just purchase the Xterra 6.8 Trail Runner…. I've logged quite a few miles on it so far, and to date have not had one issue. If you are on the fence, get off! Buy this treadmill! This tread surpasses that Sears one by light years! It's extremely heavy duty, definitely made for high mileage running. Delivery was excellent; company called a few days before to schedule time, and then called again about an hour before to make sure I was home. Delivered and set up right in my home. Wife is not crazy about the color, but found the black grows on you. If the only thing negatively you can find about a treadmill is color …. Just get over it!
