The upright walker assembled easily with the provided video. The wheels are very sturdy and I feel will hold up well walking on concrete sidewalks (a problem I had with my previous walker). I like that it can be adjusted to my height so easily. It is a joy to use, and I use it every day. If I have one criticism, it would be that the cane holder does not attach well to the walker. It is constantly coming loose while I am walking. I plan to attach it permanently with a drill and nuts and bolt. In today's world, this is not too much of a problem. Overall, I am delighted with this appliance.
