we used it last weekend.
i tossed a PBR to a buddy, unfortunately my toss was a little off resulting in a bobbled catch. the PBR was dropped resulting in a serious ding to the can just above the bottom ring.
Luckily we had some fiber fix and were able to wrap the injured area, dip the can in the river and let sit. in 10-15 minutes we were able to drink without fear of the can rupturing at the affected site.
the only down side was that my buddy had to drink a "craft beer" while waiting for the fiber fix to cure. he still has not let me live that part down.
