To start out with, they were easy to put on my walker. They roll over the threshold to my apartment and the thing that is between the carpet and the floor-- the metal strip to hold the carpet down. And they roll over the metal in the doorway to the elevator-- before I had to pick up my walker a bit to get into the elevator. Now I have to get used to my swivel wheels-- this is the first day.
When I was selecting walkers I didn't need one with a seat but I did need one that was easy to maneuver, was lightweight, & folded with ease. I already had a conventional walker so I ordered swivel wheels. What a wonderful convenience! I don't have to pick it up & put it down each time I change direction! The wheels were easy to change out & they came with tennis balls for the back legs. I'm very satisfied!
