Seemed like a heavy duty, well built machine. Very heavy. Numerous problems, #1 noisy, squeeky deck. Key's fitness (before bankruptcy) suggested spraying silicone spray around all 8 rubber deck bumpers. At approx. 1,000 miles, rubber bumpers disintegrated. #2 motor would stop abruptly, Key's fitness had me dismantle lower control unit. When elevated to 10 degrees, negative wire for the motor became tight and eventually became loose. #3 motor began slowing and speeding up. Motor eventually stopped with a burning smell. Called Key's Fitness, message said bankrupt. They would order me a new motor for $299.00 + shipping and handling and it was on back order for over a month. No guarantee. So much for the lifetime motor warranty. I can't believe Keys is still listed on various treadmill websites.
