Query: Black&Decker battery powered Caulk Gun is a blessing

I was so relieved to find this product. I glue upcycled glass for yard art and my hand ("trigger finger") was having a hard time using standard caulk gun. I looked up battery powered on amazon and was pleased to find they offered Black&Decker.What a blessing! I can be creative with less pain :) Amazon=amazing!
