I purchased this for my husband who is 83, has parkinsonism & needs a walker for balance. This one allows him to stand up straight which helps the pain in his lower back and seems much sturdier than the small rollator he has. There was a problem with one of the parts but customer service shipped a new part asap. There has been a slight learning curve for him but he has only had it for a few days. He has to remember this is a "big rig" so he has to make wider turns to avoid catching the wheels on furniture and door frames. I can see that he Oasis Space is much better for his balance.
