Both of them can use it and really enjoy it. They've noticed better blood flow in their legs too. The other residents are curious about it, and the occupational therapist even gave it a thumbs-up. The speed adjusts from 1 to 5, and it's easy for them to change the direction. The remote is quite user-friendly, so they had no trouble after I showed them how it works. This model has a handle, which is perfect since my parents need to move it between chairs. It's lighter than many other options I considered, so keep that in mind if you're also searching for elderly parents. I'm planning to get another one.
