My wife got me two pair of these from a local military surplus store.  One strap broke immediately!  It look like it was dry rotted.  The other three straps lasted over a year without issues.  One broke during its second year; the stitching came out of one of the ends, and the elastic was all dry and brittle.  I still have the final two, but they are really stretched out and dry.  I am very surprised that other men don't use these things more often, because they made my shirts look FANTASTIC!  Perhaps, if they were a more popular product, then some better quality straps would come out.  I'm going to go down to the local store and pick up a new pair sometime soon.  I might even buy a few sets, since they are so cheap, to help offset the quality.  Concept = 5 stars.  "When it works" = 6 stars! :-D  Quality = 1 to 3 stars. :-(
