I really like mine too but I do seem to have one problem with it. If I have a tube of caulk that I store for use later, after the second time I got to reuse it, I have problems with the gun getting it going. Yes, I clear the old caulk out but you can't get all of it. It doesn't have enough grunt to get the caulk moving. What I do is run the gun and help it along by pushing on the back end of the plunger to increase the chooch-factor so that it can push through the small clog. Once it gets going from there it is good to go until the tube is store again. And if you think I'm not doing a good job clearing the old stuff out, I'd argue that I am. I pulled the tube out and put it into a manual gun and he spice was flowing with little effort. Put it back in the M12 and it worked fine after that. I have tried turning up the speed to see if that would put more jam into the rotating assembly, but it didn't seem to help.I just busted out my M12 caulking gun. Awesome tool. I have been installing 4x8 1" blue board insulation on concrete. Made it super easy to spread all that adhesive on the board to stick it to the basement walls.
Works perfect. Love it.
Other than that, I love the little guy.
