Doesn't Stick
These strips will not hold the mount and the weight of a Speedlight worth a damn.  Dropped 2 Speelights trying to use these strips and their mounts as advertised, in positions and on materials that they show working on the companies website.  Fortunately, neither of them broke.  The Tether tool with the little bungee connecter also sucks, the one with the round base is cool but I even tried to use a strip to mount it to the top of a shelf with the flash leaning over and the strip wouldn' hold.  Total waste of money.
