I love this treadmill! This is treadmill I own now. I have owned it for a few months now and I am almost positive that I am in love with it! I have it set up in the corner of my house and I lose track of time while I watch the screen. Performance This treadmill works so well! I have fallen in love with this machine. It works so great and I haven't had any problems with it. Comfort This machine is so comfortable to use. I love how it's shaped and how comfortable it is to look at the screen while walking, it is at the perfect height and angle to be able to forget that you are walking and exercising and get lost in whatever you are looking at. Ease of Use It is super easy to use! If you have ever been on a treadmill before then you will be able to figure out how to use this machine. There is a slight learning curve with the technology aspect of it, but if you are used to technology in general then you won't have any problems. Durability I haven't used the machine for very long, only a few months, but so far the machine has held up well and still looks great. Design It could be more stylish, but frankly it's a treadmill, not a piece of furniture that is going to add design to my house. So while it could be more stylish, I don't really care that it isn't and wouldn't consider it a negative thing.
