The Horizon T701 Treadmill is, in general, a big hunk of junk. The quality of the machine is poor, and it feels flimsy and plastic. The treadmill I received from Horizon was defective. The threads for the bolts inside the machine itself were defective, with burrs, causing the bolts to be shredded and me not able to even put one arm on the machine. It's heavy and takes up alot of room. Over all very very cheap quality and I would definately not recommend this to anyone. Horizon's customer service is very poor, they never answer their phones, and don't bother leaving them your number to call back.... they won't. AVOID AT ALL COSTS.
