### ⭐⭐⭐⭐⭐ High quality caulk gun. Great design.
*by S***P on November 14, 2025*

Do yourself a favor and buy this! I've had so many of the crappy stamped orange or blue caulk guns that ooze caulk everywhere. This is a great gun and helps with really stiff, cold adhesives. It's built like a tank... I don't see having to replace this any time soon.
