Customer Rating: - Good insulating gun
I purchased this gun to insulate my second house. What I like most about it is that you can store the partially used can on the gun and if you keep the screw closed it will last forever. The store bought cans with the plastic hose don't last very long once open. For all around use, use the door and window insulation. The crack insulation gets harder and expands more making it better for the large openings.
