This unit was purchased to help a disabled person restore movement in arms and legs, which otherwise get no help whilst confined to a wheelchair Regarding the purchase procedure with Overstock.... Arrived in very good condition (considering this is London England, a long distance); there was no damage.The unit is very well made. The motor can be controlled to a very slow motion, smooth with no loss of power. The disabled person using it has no discomfort or fear during a session. The motor speed control has very fine adjustment .Quality of construction and materials is very high standard. Strong frame and crank; compact; easily stored. Well finished white and fits into home or medical environment.Criticisms: The voltage and power requirement need to be stated.110volt 50-60 cycle, 25 watts. In my country a transformer is needed, but this is a small low cost local item.
