We purchased this treadmill on sale at Sears after I had back surgery so I could get my walking in on smoother surfaces than outdoors. It is a powerful but space saving piece of equipment. It has a 17" by 50" belt with a 10% power incline. It also has preprogrammed walks that includes different speeds, inclines and declines. It also came with a 3 year warranty on the motor and 90 day on parts and labour . It also features a space-saving design for easy storage and is iFIT interactive personal training compatible .It also monitors your heart rate, calories burned, fat calories burned, time and distance walked. It also has an emergency kill switch that you attach to yourself in case you trip or fall, the treadmill cuts off so you do not further risk injury by moving parts. Over all it is one of the best treadmills I have ever been on, now if I can just motivate myself to start walking on it again.
