Very impressed with the quality of the machine. Durable construction with metal encasement; can be moved with attached hand grip but individual must be able to lift ten pounds. Dual application for upper body and arm rotation as well as leg rotation workouts, with simple adjustments to pedals. Can be placed on floor for lower leg activity, and also on counter/table surface for arm acitivity. Adjustable tension for increased resistance; adjustable speed for passive workout routine. Ideal home exercise equipment for individuals unable to do active movement, such as those with limited range of motion, stroke impairment, incapacity for active ambulation, lower limb DVT (deep vein thrombosis), etc. Individual should be assisted with this equipment during its use.
