Works great. Very easy to use and the pen flows smoothly with no effort but I wouldn't say it doesn't drip. It still drips a little after removing the hose from the caulking gun. Again, I'm still a beginner when it comes to minting. As long as I time the trigger and trigger and remember that some sealant will spill out, I can work with it. You should practice a little before using it. In general I am satisfied.
