I love it. Walking without much pain is fantastic. They now have a larger size which would be great for larger people. It does loosen up when walking around on uneven surfaces like a lawn, park, etc. No big deal, just tighten everything up. I can tell when something is loose. I love the shopping bag accessory. Nice for farm markets, bazaars, books; anytime you have additional things to carry. Doesn't work on sand but my feet don't work either. It's the best investment I've made in a long time.
