Query: Manual Treadmill

Nice treadmill for the money...but a word here...BUY THE SILICONE SPRAY. This rides at a bit more of an incline that I would like it to, but MAN. Do you get a workout on this thing! By the time you've gone a half a mile on this, it would be like a mile on a regular walk, and does not take long to break a sweat! It is NOT, however, a treadmill for running or for someone with balance issues. Assembly is VERY easy, and with the easy-up feature for the belt base, it stores nicely. The pin that locks it in place for storage has a potential to slip, so be sure that it isn't stored in a high traffic area, or where small children could bump the machine and dislodge the belt base.
