This treadmill has lots of bells and whistles, including a bluetooth speaker (which is o.k., but not nearly loud enough), big cupholders, and a plethora of workout options and settings. It is pretty heavy duty and the guy who set it up said it was one of the more heavy duty ones he’s seen, especially for less than $2,000.
