"The applicator was easy to use, the hose attachment worked fine for me, and it went on evenly without leaking. Only thing I'd add is to run your hose for a few seconds, then stop the water again before connecting it to the sprayer. My hose had some lawn gunk somewhere along it's run, and that gunk got sucked into the sprayer when I first turned it on and it took me a while with a paperclip to get all of it out. After that it worked great."
