@Ladylurk. Maybe Hugo is not a great brand. It works for me and I am sorry you got a lemon.

DH assembled mine and a physical therapist looked it is to adjust it to the right height. I have had zero issues with it. Truthfully, I have not had any experiences with another rollator to really be a good judge.
When I am ready for the Mercedes Benz version, I am going to use you as my reference!
