The treadmill is upgraded and has more than 12 programs in addition to a USB port, and there is an incline option as if you are walking on elevated ground with 5 levels of elevation. It also has a back massage device and weight holders. The weights are present but I removed them for safety reasons. + One end of the treadmill has a plastic connector broken from transportation, but this never affected the device, and the treadmill is in good condition and fully functional. I want to sell it due to no need, not because of its quality. Honesty is really wonderful
