kill's most weeds

I bought this to tackle those annoying weeds growing in awkward spots around the drive and patio. It killed most of them with single dowsing. The more persistent ones needed two treatments. Tried it on brambles, did not work on these just killed the leaves, not the whole plant.

have sprayed a huge area of weeds in a unkept part of our garden twice and its had no effect on anything. The patch of weeds and unwanted plants includes dandelion, clover,grass, nettles, ivy, fox gloves, forget me nots, bind weed and much more. after two weeks of waiting for something to happen the weeds and plants are looking lush and green.

sprayed the entire bottle on a 2x2ft area and 1 day later, some leaves had brown spots or look dead, stoke had some brown patches but the weed was not killed. Had to buy another product and it worked like the label says. will not buy Roundup again.
