The magnets are so strong it is next to impossible to 1) get them apart for placing the rhinestone side on top of the shoe, and  2) get the bottom magnet in position under the top piece -- once you get the bottom magnet even near the top piece, the magnet's force pulls the top towards it, so it's a constant effort to get the rhinestone top in the desired position on the shoe.

Basically a waste of money, couldn't use them.  Give me the standard, old-fashioned clips style instead!
