I spent a lot of time researching before buying my Landice treadmill. There are many good features to it, but the best is the lifetime warranty on parts. It is so well built that I doubt if I'll ever have to use it, but it's nice to know I have it. Another feature I found in researching is that it has a shock absorption system that is based on medical research. It is five times softer than grass. Another good feature is that I can put in my weight and it tells me the number of calories I burn. Performance I like the stability of this treadmill. It doesn't move around while I'm running on it. I have compared it to the ones at the gym, and this one is much more stable. Comfort Because of the shock absorption system, it is very comfortable. Ease of Use The controls on this treadmill are very easy to use. Durability It seems like it will be a long lasting piece of equipment because of the quality of it. Design It is wider and longer than the treadmills I use at the gym. It has a space for my ipod, phone, a book and a water bottle.
