I am definitely a fan of these ear seeds. They're small and discreet - even my bf is fine using them. The adhesive is definitely strong. I don't have an issue with them staying on on the flatter parts of my ears or the inner ear (except when wearing headphones I think they move around some), but it's easy for hair to get stuck under the adhesive on other parts of the ear and cause the seeds to come loose.

My two complaints would be (1) that I didn't really need to buy the tweezers, but they are nice quality; and (2) that the ear seed map doesn't contain more points.
