We've only had the 4000i for about 2 weeks but so far it exceeds my expectations. This is the 3rd treadmill we have owned and they get used daily. Our other treadmills ran about the same price but this is the quietest and most solid of the 3. If this holds up for about 10 years as the others did I will be very pleased.
