Seems relatively ineffective,
This review is from: Scotts Miracle-Gro Roundup Fast Action Weedkiller Ready To Use Spray, 3 L (Garden & Outdoors)
From most reviews this seemed to be an effective weedkiller, but after about three weeks, I find even small weeds growing at the edges of paths have failed to die back. Bigger weeds in a pathway outside our house seem completely unaffected. There was no rain immediately after the application, but a week or so later some heavy rain so maybe that is the explanation. Once you've got the system set up and opened, it is a quite elegant system. Maybe I just didn't use enough (after all it is quite expensive). It's a bit of a mystery as clearly other people found it very good. But for me, not a great purchase.
