Overall, I love the machine. This treadmill isn't as expensive as the most high tech-treadmills out there, but it's not the best treadmill I've ever used. The machine works very well in helping you exercise and has many settings to increase the speed. However, after a few years of use, many of the functions of the machine begin to stop working. Otherwise, it's easy to adjust to this machine even though there's not really a place to put your iPod. It's very comfortable and easy to use, and you get what you pay for! Performance Works very well to help you practice your running skills and works well to challenge yourself. Comfort Very comfortable to use Ease of Use Very easy to learn how to use, although some of the settings can be confusing. Durability It is able to withstand a lot of things, but it does wear done after a while and loses important functions. Design The design is very simple and not as sleek or high tech as many new models. However, it's good for the price.
