One of my favorite toys for nipples. Very small, intense area of contact. Best for small nipples, e.g. most men. For larger nipples, you may find that they don't get wide enough and make contact in too small an area.
Only reason it doesn't get 5 stars is that one of mine wore out after a couple of years - the screw no longer works!
ADMIN: We are sorry to hear that the EClip only appears to have lasted a couple of years!
