The attachment is simple to use, great having the option of direct and wide spray for different applications, easy to use with simple instructions.
Sprayed this on the leaves as the instructions state. I was worried I would need to re-apply as it rained that evening but in a few days it had worked. this bottle goes a long way.
Great price, really good weed killer spray straight from the containe
Most weeds were killed within 24hrs. Seemed to prevent regrowth too.
I have tried other weed killers, but this is the best. Would definitely recommend
Easy to use, but do use a mask with this and I used gloves.
It did what I wanted to full affect I will buy again smile
This product was well labelled and with easy to follow instructions was simple to use. My weeds were dead within one day and I wouldn’t hesitate to recommend it to anyone
Spray on weeds – weeds die. Quick too. What more can you want. Instructions on where to twist the nozzle bit on the bottle end could be clearer but that’s nit-picking
My own garden had totally overgrown with uncontrollable weeds because I had pebbles laid down all over my garden to cut out the job of having to mow the grass.
But a couple of years ago in one of storms my 6 foot high wooden fence was blown down onto the pebbles and the Housing Association didn’t get to it because of the multitude of other fences blowing down.
But it took about 18 months of time to get to my address and erect a completely new wooden fence, but when they did do the array of various weeds had been growing underneath the fencing hence my current problem of overgrown weeds of all varieties.
But thankfully Roundup as been totally killing the Brambles and other weeds.
Use this to kill off pesky weeds in paths around my home. It works a treat give it a day or so you’ll see the weeds wilting within a week they are completely dead.
Only thing I was disappointed with ,was they there was no plastic clip on the handle to house the trigger mechanism when not in use,so the whole thing is just lying on the floor/shelf.All the ones I have had previously from other outlets do have the clip. Otherwise everything was ok.
I wanted this as a general weedkiller. I get it fitted togther and then sought to use it. Instructions say flip up the spout. Mmm, well not possible. Instead turn the cap anti-clockwise and it works. Shame that they could not be bothered to correct it from older models so 1 star off. Effectiveness? well, I have put it on though conditions are not optimal. Finger crossed.
