This is amazing! I had the honor of being able to test this product (see the review I sent to Darcy at http://www.tombihn.com/page/001/PROD/ACC/TB0530
I have to say, It is the best investment in an accessory you can make! It will work on any strap that is 1 1/2 in webbing. How versatile is that?!?!?! Hmmm...endless possibilities? I did try using it in a Walmart plastic bag that was large and heavy and guess what? It worked beautifully and saved my hand! Not sure if it was ever intended for this type of bag but it did solve my problem!
