It works for me. I have used the same one multiple times now and it's still holding strong. I have thick, very long, almost waist length hair. It could be a reason why it works for me but not others. I don't think this will work for people with thinner hair. It's pretty secure I don't even have to do the extra twist to keep my hair up. The wire inside does feel a little brittle though so time will tell on how long each bun holder lasts.
