This is a well made caulking gun, but it's far from perfect. The mechanism relieves pressure on the cartridge when the trigger is released, so the hose is no longer subjected to pressure and flow. But that also makes it difficult to apply enough pressure with thicker sealants - the rod simply won't move under high pressure. And thinner sealants will still drip no matter what. The hanging hook and easy loading is nice. The stem length is barely long enough for some sealers and not long enough for some of the more professional long-nose sealers. I'm still looking for the "best" cartridge gun.
