I've had my TR1200-DT3 for about 6 months. I should have bought one of these a LONG time ago! It's easy to set up and use. The treadmill is super quiet and I generally go 1 mph while I work. A very easy pace. I walk for half my work day and stand through the other 4 hours. My health has improved greatly and this machine has worked flawlessly. I have no idea how long it will last, but when it eventually wears out (whenever that might be), I plan to buy another. I highly recommend this product.
