Bought it on Amazon in for $400 and it has done quite well. This treadmill makes a clicking noise, especially at lower speeds. According to Google, it can be a bad bearing, the belt may be passing over the rollers, there may be loose bolts, or the rollers may be worn out/damaged. A couple of the buttons have faded paint. There is a Bluetooth speaker, but I unplugged the cable because the speakers kept connecting to our upstairs neighbors music player. You can easily plug it back in by unscrewing the front portion. The treadmill has a 2.5HP powerful motor that will allow you to go from 0.6 MPH to 7.6 MPH. The 17 inch widened buffer strip design, multi-layer rebound damping makes your running more comfortable.
