Used twice since new. It has been stored at home for a while. A balance walker (also known as a slackline) is a sport where you walk on a line like a tightrope walker. It not only develops your sense of balance but also strengthens your core muscles that you don't usually use. Since you only walk on the line, adults and children can enjoy it together. It's also compact and easy to carry, making it a recommended gear for camping activities.
