I work in a hospital and often push objects while walking. I found that my Fitbit would not accurately count my steps when my hands were on a cart or other object that I was spinning. So I made her wear the Fitbit on my ankle (that's why I bought the big ones). For my purpose they are great. I just place it on my ankle before putting my shoes on and even forget it's there. I figured it would be easier than a buckle and more convenient. It works great for its intended purpose.
