The Horizon T303 is the Third Place Best Buy Winner in the $1,000 to $1,499 price range and is a quality folding treadmill containing many features to please consumers of most all fitness levels.

Overall Quality

The Horizon T303 has a quiet yet powerful motor that recalibrates every time your foot hits the tread and allows high speeds of up to 12 MPH. A 20” x 60” deck gives consumers room to stretch their stride as they climb to a lofty 12% incline for countless hours of challenging workout sessions. Shock absorbency limits painful footfalls to a minimum and the FeatherLight ™ folding feature is optimal for those with smaller exercise spaces.
The console on the T303 is updated with interval keys for setting up two individual HIIT training sessions, which are then personalized with the chosen speed and incline for a quick entrance to exercise fun. Heart rate monitors are handy on the middle bar, keeping users on track and the console is easy to read as well as a font of important workout data! In addition, Bluetooth capabilities allow users to partner with fitness apps for on demand classes or just watch a movie as they walk or jog their way to fitness glory. Last but certainly not least, there is an integrated fan, tablet holder, and water bottle holder for added convenience.
