Works fine.  My solution to those reviews that say that clothes catch onto the pointed edges and get torn, is to make sure you press down on the 2 ends with both thumbs as you put it into lace.  And take some sandpaper and dull the pointed edges that (might) stick out.  Problem solved! Gave it 4 stars only because you have to do those 2 small things.  Otherwise, it's fine.
