Purchased on Rakuten. This was used at home, but I think there's little wear and tear because I used it with room socks on. There are a few small stains. I've wiped the whole thing down with isopropyl alcohol. Button operation and counting are also fine. A belt is also included, so you can add more resistance than normal walking. How about it for maintaining your health, dieting, or when you don't want to go outside because it's cold, especially since it's easy to gain weight during the New Year's holiday?
