Query: Good Sprayer, but doesn't kill weeds...

I was a bit disappointed with this products. As the title says, the sprayer works very well. Pull out the handle, and then all you have to do is point the nozzle and pull the trigger. It was actually mildly enjoyable to "shoot" the weeds. So I gave it an extra star for this...That said, it did nothing to kill my weeds. I've used Weed B Gon for two years in a row following the directions explicitly, but all my dandelions are still here. They wilted for a couple days after applications, but were soon back to full strength. I made two applications as suggested... still no luck. My neighbor pays a lawn service to come care for his lawn twice a year and his lawn looks amazing. While I have not checked pricing, I would bet two visits per year from a professional lawn service would be similar in cost to multiple applications of this stuff.
