I've had these for a month or so now, wearing them about 3 times a week.  I like my jewelry simple & not too "girly", and these are perfect.  There's still a little space between the bottom of my earlobe and the earrings, I could go maybe a mm smaller & still have a good fit (adult female).  They snap securely closed and have never come open thru hair brushing, showering and pulling shirts off & on.  I tend to have problems with cheaper earrings making my ears sore, red & irritated.  Have had no problems at all with these, which is what I was hoping for.  Will probably buy more in different colors.  My only complaint (if you could call it that) is that they come packaged just the 2 earrings in a thin little covering & it is a TINY little package.  Mine came shipped with some other items I ordered, and are so small that one pair slipped between the box flap and the box & they almost got thrown out.  I'm glad I checked the packing slip & noticed the earrings were in that shipment.  Thought they forgot to include them.
