Horizon T101 Treadmill vs Sunny Health & Fitness Slim Auto Incline Treadmill

The Horizon T101 is the better treadmill for most people: a 2.5 hp motor, a 20x55-inch cushioned deck, 10% incline and app support through Bluetooth. The Sunny is lighter and more compact with a slightly steeper 12-level incline, but its 2.0 peak hp motor and 9 mph top speed suit walking and light jogging only. Owners praise the Horizon's quiet, sturdy feel and easy setup, but some report control panel failures and warranty disputes. The Sunny has far fewer ratings, so its 3.8 score is less settled.

• Choose the Horizon T101 if you want a proven, quiet treadmill for running, app classes and a wider cushioned deck.
• Choose the Sunny Health & Fitness Interactive Slim if you want a lighter, more compact folding machine for walking and jogging with a steeper incline.
