Sunny SF-T1407M vs SF-T7723: which manual treadmill?

Both are manual, non-motorized treadmills: the belt only moves because you move it, so there is no motor to plug in or burn out.

The T7723 costs a band more and answers with dual flywheels and a slightly wider, longer belt (43" x 13.5" vs 42" x 13"). The T1407M keeps two manual incline positions and the lower price.

FAQ

Do manual treadmills need power?
No. Neither has a motor, so there is no plug, no motor noise and nothing to fail electrically. The trade is that you supply all the force.
Are manual treadmills harder work?
Yes. Driving the belt yourself takes more effort per mile than a motorized pad at the same speed.
Can either be used under a desk?
No. Both have handrails and stand too tall to slide under a desk.
Which has more incline?
The T1407M offers two manual incline positions; the T7723 has a fixed slope.
