Bought these for a tween who refuses to tie his shoes.  Nearly as easy to install as shoelaces although the clip at the end (that keeps the ends together) takes some strength to close & I'm not sure how to get it open again if need be.  Still work just as described and look a lot better than flopping laces (safer too).  Followed other reviewer's advice to leave the ends long & tuck under the laces.  Bought the black to go on all black shoes - they aren't glaringly obvious but the lock & clip are noticeable if you look.  Still, my picky, sensitive to odd sensations kid is happy with the laces - as am I.
