It really works.  But it's tricky to cut and apply without the fabric sticking out from the nail.  What I do is to apply the glue as per instructions and then when it is all dry to file off the part that is sticking out.  You definitely need very fine scissors and a steady hand, but it is the most efficient nail mender I have found so far.  I'd recommend it to guitar players and anyone who cannot afford to have nails breaking.
