[EX Q]: Unfortunately they didn’t work for me at all for they doesn’t work with soft tissue. My skin tissue is too soft and it won’t stay in place. So be careful unfortunately it won’t work for everyone. The firmer your skin is the better it may work.
[EX A]: negative

[EX Q]: I bought this for a friend who planned to travel outside the country. I told her it was to wear in case she was robbed--in the event a loss but not a GREAT loss. It is so pretty she was worried it would invite a robbery! (She wasn't robbed but really enjoyed wearing it.)
[EX A]: positive

[EX Q]: I have gone through two of these ear pieces... not because I like it but because they get lost very easily.

negative
