solder globbed on like the guy was icing a cake" is about the best way I have heard that put. And yeah it drives me nuts because it is everywhere now, not just plumbing. Went to get my truck tires rotated last month and watched the kid run the impact gun on the lugs like he was in a race, cross threaded two of them and shrugged. Same deal at the deli counter, guy slicing roast beef so fast the pieces look like confetti. Nobody slows down anymore, everybody just wants to be done. Trouble is with copper, done too fast means you are cutting it all out later, and I would make them pull every joint they touched, not just the ones you can see. You can not unsee sloppy work once you know it is hiding back there.

Man that depth stop is the sneakiest thing on those tools. I ran into the same deal with my own setup, kept blaming the cable or the connectors for months when it was just me being lazy about checking the dial. Once you hit that right notch it feels like a whole different tool, strips like butter. Also worth doing a quick test strip every time you change jobs or spools, cheap insurance against pulling your hair out later.
