Bests & Worsts Reviews from Amazon

It's glyphosate, it kills weeds. Vastly cheaper than buying readymade, stupidly dilute off the shelf products. Even with buying this and a gallon sprayer, you're saving money (and getting better results) on your second spraying. Just remember, it's glyphosate, so you need to be careful, and patient. Mix to the recommended strength - there's no advantage to making it stronger. Spray on a dry day without a strong breeze, ideally early in the morning. The weeds will transpire during the day sucking in all the glyphosate, and will start to shrivel within two weeks.
