We are very, very happy with our choice of Walkin' Wheels. I did as much research as I could online before making this choice. Adjustability was a big factor because of Sol's 80lb. size. Also, I was anxious to get it quickly before Sol lost more function. He is way happier being able to walk freely with us again. We use the same harness that attaches to the frame to help him walk when he is in the house (without the wheels/frame). Mimi has been a great help with suggestions on how to adjust the frame and straps to get it just right. We sent her a photo and she emailed back a list of her observations, which were a big help.
