Due to the fact that I often do DIY projects at home, ranging from artistic interests to various small repairs, I have changed about 15 or so such guns in my life so far. Well, this is one of my bad purchases because it has the characteristic that I despise in silicone guns. When the nozzle dispenses glue, it does not stop the flow abruptly. You press the trigger, and it dispenses the glue without cutting off the flow when you release the trigger... Stay away from this gun if you can, even if you can fix it and see that the nozzle still drips... Also, within a month, the nozzle gets clogged, and even though I frequently check and maintain the gun, it still does not have an easy and smooth flow...
