I bought this for a family member who has a spinal cord injury and has developed spasticity in both legs. He is unable to stand for long due to weak legs and is unable to get much movement due to this. I thought this would be great for him to do while watching tv and in between Physical Therapy appointments.He has no strength in the legs to manual move pedals. This turns on with a remote and automatically moves his legs for him. And the unit does not slide on the hard floor. Other brands we tried would slide on the hard wood floor.It is a bit heavy for someone who does not have much strength to pick up. So, he will need someone to grab it for him and place it in front of him and plug it in. After that he can use the remote to turn on and use (make sure to add 2 AAA batteries in the remote which is not included).The only thing I wish it had was straps for his feet to stay on the pedals, just incase his feet cannot stay on when they spasm or flex on their own. For now, he uses his walking stick to press his foot down incase that is needed.Overall, he loves it and uses it 3 times a day for a few minutes forwards and backwards and he can feel his knees, joints and legs getting movement. I can visibly see his knees and even hip flexors rotating- almost as if he is sitting on an exercise bike. He currently is using it on level 1 (slowest level). Some reviewers said the machine was loud - I am pretty lucky because mine is very quiet - and hardly makes any noise when plugged in and using it on auto.Update - he is still using it, still quiet, and now has been able to get to level 3. Someone wasn’t always there to bring it to him, so we plugged it in to a surge protector and put it in a corner in the room and now he wheels himself over and uses his stick to press the surge protector on or off when not using it.
