OMG! This Stuff Really Works!
OMG! This product really works. I am in orbit! We had bind weed, ground elder and something else that was persistent. This stuff killed it off. Few bits trying to come through but very little and I zap it straight away never to be seen again. I really thought that we would never get rid of those weeds and briar. The container is also very good. It is sealed and it comes with its own spray gun.

Worked well on ragwort
I bought this to (carefully) spot spray ragwort in my horses field as a back up after having it professionally sprayed with dicamba a month before. Ragwort being ragwort had pretended to die then rose like a phoenix from the ashes at the first sign of rain. It worked quite well although its hard work if you’re doing a large area by hand.. if the lance were longer it would have been so much easier. The sprayer worked well though.. I didn’t have any issues with it dripping or not working.. I just wish it had been longer so I didn’t have to continually bend over. The hose is long enough but the actual sprayer itself would benefit from being a lance rather than just a trigger. It did kill a lot of it.. some of the bigger plants survived the first spray but that’s ragwort for you.. if there were a nuclear incident it would be the ragwort that survived it. They seem to have died after the second though.. yay! It worked quickly.. the plants started to turn brown and die within a couple of days . They’ll probably come back though .. scientists should study ragwort if they want to unlock the secret of eternal life. I spot sprayed about 3/4 of a 4 acre field.. probably well over a hundred plants, and I sprayed them very generously so it does go a long way. My back gave out before I finished the container.. there wasn’t much left but enough to do at least another 20 plants a week later. I can’t say how well it works on other weeds as I was purely targeting ragwort but if it kills that it’ll kill anything, up to and including Triffids. If you’re just buying it to do your garden or driveway then the design will be fine, but if you’re aiming to do a bigger area I’d decant it into a sprayer with a long lance or buy the concentrate and again use a sprayer with a long lance and a shoulder strap.

Problem fitting sprayer
I had great difficulty in fitting the sprayer to the container. I'm sure there is a knack to it but in the end I gave up. I have used the product before and had retained a smaller sprayer. I was forced to decant from this container into the smaller sprayer. I'm happy with the product. It works very well on most weeds. Some of the more hardy weeds do require a repeat spraying.

Killed most of the weeds
Bought this to kill weeds all over (drive, paths, rockery), including some ivy that sprouts up everywhere. It killed some of the ivy and most of the weeds but some weeds seem to have resisted it, hence the 4 star. There are two spray options, one is like a water pistol and the other more of a conventional spray. It's easy enough to use and one thing I liked is that they recommend using it for 8 hours before any rain. The last one I bought (different make) recommends 3 days - what in the UK? I used about a third of it so can have another two goes. Would I buy again, probably if the next time I use it, it gets rid of what I spray with it.
