Brunnings crap

I use a lot of daily products, shit I should be working for 'choice' magazine.
Some are good or bad or [ dare I say it ] ugly?. Any who, now and again I come across some products that apparently slip by the bodies that investigate things to see you get WHAT YOU PAID FOR !!.
I have several BRUNNINGS products on the shelf and mostly bought from different stores but around about the same time as I am doing a sh*t load of renovations and landscaping. I bought BRUNNINGS rose spray for the 'wozes' and path weed killer for the concrete. Neither of these products is worth a pinch of sh*t !!. The rose spray did jack and I practically emptied the bottle of weed killer on one patch - nufin, I could have drunk the stuff myself as not so much as a stinking leaf withered in a week. The roses were looking worse so I switched to white oil and that did the trick in 48 hrs. Upon examining the contents of both bottles, I found the apparent formula CONCENTRATIONS were so bloody diluted, It's a wonder the stuff is allowed to be sold claiming what it's supposed to do. I had a bad experience with ANOTHER BRUNNINGS product but threw it out in disgust and can't even remember what It was. BRUNNINGS products are crap - diluted to buggery - don't do the job unless you use liters of the crap to drown the weeds. Best bet, buy the super concentrate you dilute yourself, then use it straight. I found this does the job nicely. But I ask myself - why do these products exist if they are as weak as horse piss ??. Why are you charged a sh*t load for a concentrated product that does NEAT what the others claim they will do in a ready mix.
The answer is simple, its a blatant rip off [ that was easy ]. Just like the big MILK rip off that;s coming to light NOW, the powers that be had better start investigating ALL home products that make certain claims but can't cut it because the formula in the container won't produce the results claimed in the DOSAGE recommended. The formula on the packaging may be correct [ no fraud here ] but the claim is bull sh*t by trial and error in the field. The stuff may kill your prized Petunia but as for hardy weeds; forget it.
