I bought these to wear two of them myself to Zumba class and to give the other six to friends.  Everyone at the class I wore them to loved them - - at first.  Those little bells are surprisingly noisy and started to get on people's nerves after a couple of songs so I took them off.  One bracelet might be better.  I personally love the sound but I will make sure in future I am aware of the fact that not everyone might think they are as fun as I do and will wear them for short periods.
