Under 45 dB from a 2.5 HP brushless motor is the number that makes this pad usable during calls. Speeds run 0.6 to 4 mph across a 36-in by 15-in belt, with seven belt layers and six rubber shock pads underneath to spare the knees and ankles. Three countdown modes let a session end on time, distance or calories rather than watching the clock. The LED readout covers speed, time, distance and calories, and the remote adjusts everything without breaking stride. At 43-in W by 19-in D and only 4.7 in tall, the white deck slides under a sofa or a bed; it weighs 36 lbs and takes users up to 220 lbs. A 5.6-ft cord reaches an AC 110 V outlet.
