I have a gym membership, but during the week it is nearly impossible for me to get there. I wanted a simple treadmill to use during the week that would not take up too much space and would not require a Phd in engineering to operate. On all accounts this fits the bill. Small enough to fit in a bedroom, it is also very easy to use. I always employ the quick start option. I don't bother to use the cardio and varied workout features. My sister came over and tried some of the more advanced workout options and said it would probably be easier to just hop on and start using it. Performance Its got what I need, a belt, handles, and a readout. I don't really need my treadmill to do much more. Comfort To be honest, you are on this thing to exercise and exercise is never really comfortable. The tread is decent, a little tough to push depending on your incline, but the handles are easy to grip. Ease of Use I don't fool around when I want to get a workout done. I get on, adjust the speed and the incline. I watch the time more than I do the distance. But the readout is simple enough to understand if you want to get specific data. Durability I want to give a disclaimer, I have owned this treadmill for less than a year. So far I have not had any issues of parts breaking off. It is certainly not as durable or steady as the ones I see in the gym, but for myself it certainly suits its purpose. Design The handles are at a good height for me. I am 5'4. The panel is also at a good height. Its high enough to touch the buttons without reaching and I can rest my Kindle on it for eye level reading.
