I've used this a few times. It's really shorter to use and works just as well as any weapon I've used in the past. I will say that it drips just like any other weapon. The so-called anti-drip function is exactly the same as with any other gun: pressure relief. The only difference is that you use your index finger instead of your thumb to press on it (6 of a...). I found this not to be a problem. The piston that slides the hose inwards is in front of the knife that separates the hose, so the cut, no matter how long, is always far behind the active part of the sealant hose. My only concern is how long it will last as it includes a blade (which cannot be sharpened) that will split the pipes. It should dull over time. The time will show.
