It’s a good weed kille
My normal weed killer, does exactly what it says it does and this time Amazon had the best price around and it was delivered to my door. What more can you ask.
Weed killer.
Great product only use this product when the sun is out and hot,and only spray wear the weed is not the around the weed,the product has no smell.
Great at killing weeds and a very good price from amazon. The pump is the only thing I wasn’t impressed with. Unless your really strong it takes a lot of effort to get the liquid flowing strongly.
I had a huge issue in my front garden as dandelions were all over the path and other weeds. I have constantly spent time taking the weeds out by the roots to no avail. I decided to buy this product as a last resort. Having used this product, it should have been my first resort! This product is easy to use. 20 to 30 pumps lasts for around 10 minutes. I was pleasantly surprised as the product had a slow flow of liquid instead of a spray. I would advise not to use this on a windy day as it can blow onto areas you don’t want. I gave it 2 or 3 days and every single weed was dead. 4 months later and there has been no regrowth. This is one of the best products out there and will save you a lot of time and effort! Well worth the price!
Does the job well
Used this before and it’s does work fast, no issues fast delivery, I do empty into a large sprayer as I have a large path but it’s fine to use the sprayer that it comes with. Would recommend .
Does the job
This is my third purchase. And finally, I have a sprayer that works! Weed killer is pretty efficient. I have done it twice And now keep on top of it every few weeks, so nothing grows back in the meantime Easy to apply And works within a few days
Wonderful Stuff!
I have always had a problem with a weed called Horse tail, or Mares tail. Over a number of years I tried many many treatments- both enviro-friendly & not so friendly.
I think that this stuff had really done the job this time!! Only time will tell, I’m excited to see if it appears again next yea
Killed bramble and bracken.
It took two coats over four days to kill bramble, dandelion and other popular weeds.
Even killed the weed in my drive, there no sign of them after three weeks, amazing.
The spray system is also easy to use and I have purchased a refill, I thought the refill would have slightly cheaper but never the less it is a good product.
Works well; see review.
Nothing wrong with this product, but I could not remove the lid and pump assembly from the sprayer in order to refill it, it was completely gummed up. Therefore, check you can remove the lid etc. from your sprayer before buying a refill. In the end I bought another sprayer and kept loosening the lid, then was able to remove the lid at refill time.
Great weed killer!
This is my 2nd purchase as I had to get rid of a lot of pesky weeds. This is very easy to use and I have experience no leakage from this so far. After about 15 also you are ready to spray the weedkiller! The prices a bit much, but it certainly does the job!
Worth every penny
Fantastic product that works in hours, best to use on a hot day when no rain is due. I used on stubborn large weeds and after 4 hours they had all gone brown after a week they are very dead. The little included spray gun and pump action bottle works great, it dispenses just the right amount so the bottle goes along way.
Weed kille
Value for money and good size.i
I had abit of trouble with the hose but easy to use and no leakage and no after colour. Good for gravel garden’s and paving eg patios. Quality of the weed killer is excellent and works quickly
Had bad issue with grass growing down the edge of my artificial lawn. This stuff killed it quickly and now edge of lawn is great. Only issue is the sprayer isn’t the bes
Wow wow wow
In-between the cracks in my backyard grew enormous weeds I couldn’t keep on top of them they were an eyesore for years I tried all sorts of remedies with no joy but this stuff wow its so easy to do and after 24 hours the weeds had shrunk after 48 hours you could hardly see them I just scraped the dead weeds out and it looks fab its been 2 weeks with no return of the weeds give it a go
This is a brilliant product, it’s design & build are brilliant with the push button pull out & close spout, it’s handle with it’s twist lock & it’s easy pump, jeez even the spray hose holds it’s wound position to place back in a section built into the tub for it.
Now for the product inside the tub & design, well, it works! It works extremely well, I just pumped away around 6 – 7 in the evening & sprayed along the all of the gaps in between the paving slabs on the patio & on the entry alongside the house & down the path that’s entrance to property & the next day I could see life leaving some of the smaller weeds, fast forward a few days & with a shovel & brush I removed the dead weeds leaving the areas that I have mentioned in this review completely weed free, I will definitely be buying this again when I’ve used up the rest of this first tub as the tubs quite large so it’s big enough to house plenty of the product in there, for example after I sprayed what I mentioned just going across the gaps in the paving slabs there’s still around about a little over a quarter of the tub left which I’ll use on any returning weeds if there are any?
And the product leaves a clear or clean kind of mark where you’ve sprayed it if it’s on paving & probably decking but it goes naturally after a couple of days, I just thought that I would mention that.
A great buy as it’s an excellent product, a 5* product all of & in every way.
EDIT: I used up the remainder of the product on an old small rockery area that I forgot that we had as it was so overgrown with weeds as no weeds had returned at all from where I mentioned in my initial Review & it killed off the smaller weeds there whilst leaving the larger ones so much easier to remove above ground & then it was a case of removing what was left below ground from the larger weeds that just tied in with turning & airing the soil.
I’m still 100% behind this product probably even more so PLUS the large green weed killer housing tank on this spray is recyclable!
Does what it says
I have a small garden but have left it for 9 months due to losing my partner
I had literally hundreds of dandelion and stinger nettles and what made it worse was starting to get growth coming through my false grass
I sprayed it on each area of weeds on a dry and sunny morningand within a couple of hours could see the weeds wilting and the stinger nettles where the first to turn black
I left it 24 hrs during which it rained in the late afternoon came back to it am2 days later and the weeds and wild grass including the ones between the flagging came out so easy
I have 3 cats and kept them in until dry the following day and they are ok
Would recommend i
Eradicate pesky weeds
Great built in pump for easy use and portability.
Worked on brick paving, concrete paths, cobble and tarmac’s drives, after a few days the weeds are purged and gardens and drives look in far better conditio
The only one that actually worked
This year because of the strange weather, the weeds really took a hold on our shingle driveway. I could see it turning greener by the day. We tried this and that and it didn’t make a difference, the weeds just kept growing. Then I bought Roundup which is a bit expensive but there again IT WORKED. We used it 2-3 times during the growing months and it managed to keep the driveway clear.
Highly effective on a wide range of pesky weeds!
There’s no doubt that Roundup weedkiller does exactly what it proports to. Indeed, I have used it to great effect on the likes of nettles, ivy and even bamboo – although repeat doses maybe required. Highly recommended.
Pretty Powerful Stuff
Certainly killed the weeds, though how long they will stay dead is to early to comment. Be very careful though not to get it close to grass or flowers etc as the liquid will spread and kill any vegetation it touches. Watch out for drips too. I hope the periphery my lawn recovers next year! My mistake.
I have tried so many environmentally friendly weed killers off the shelf, spent a fortune and found nothing to kill weeds and grass on my paving. Tried all kinds of concoctions. I knew I needed some heavy duty stuff that says what it says on the bottle ‘kills’. Against all advice I bought this Roundup Fast Action Weedkiller Pump ‘N Go Ready To Use Spray, 5 Litre It is the best thing I have done. I have struggled for years, spending half my summers sorting out my drive paving as mine was the absolute worst in the street. I have now got what I deserve, weed and grass free. I shall for sure keep on using this product ‘only when needed’. I am Sorry environment.
It really does work...
I have expensive Old York Flag Stones as half of my court yard garden… which is very large. Approx twice a year the weeds spring up between them. As i get older, i sometimes find it harder to de-weed the gaps and i find that instead of always, just pulling the weeds, i now need to do as much as i can and then use this product to finish it off. I have just done this for the Autumn and the garden looks great, with no sign of re-growth!
Good weedkiller!
Does exactly what it is supposed to do.
sadly mine arrived with the pump handle broken in half – I managed a glued fix but the packaging could do with being more sturdy for the weight of the product – which makes it expensive for what it is.
Only use when dry weather will last at least 6 hours after use
This is an excellent and easy to use weed killer where digging would disrupt other plants. Also used early enough it will prevent weeds growing to excess to the point where major digging is necessary
Kille
Effect on weeds thought is was bad when I used this for the first time it rained within a hour of useing three weeks went by and the weeds where all dieing round killed them. Quality Damage done.
Kills everything In my garde
Brambles; my garden looked like a cross between the overgrown castle in ‘sleeping beauty’ and the island in ‘Jurassic Park’ but that didn’t stop this murder-water from turning green to brown.
We have a garden back thanks to this stuff
100% Death
Very effective on clearing weeds as it kills down to the root. I found that one application was all that was needed.
There was no staining on or around fencing or slabs when used and was easy to use with a garden sprayer.
Good all round weed killer.
Have used this product for some years to clear weeds on drives and paths. I think it is the most effective one about. Saves having to mess about with trowels and forks. You need spray equipment to use as it is just supplied as liquid. Needs a few hours of dry weather and preferably some sunshine after application to be really effective.
Does its job.
Ever since my first purchase of Roundup, many years ago I have always used Roundup, as it is fast acting, usually within 2 to 3 days. I have since moved to a new property and the garden was overgrown with weeds, nettles and brambles the weeds were visibly dying in 24 hours the nettles and brambles took longer. It was a big job so I poured the refill bottle into my own sprayer because I find the nozzle on the conventional sprayer to have issues.
This is easy to assemble and use , but even after pumping it for 30 times at least for the spray , it is still very feeble and the pump does not last 10mins as stated , but what I have sprayed is dying back , but as long as you know the spray is feeble it will take longer than stated.
Does what I bought it for to kill weeds but it’s not very sturdy cheap plastic pump action and the so called extendable wand is too short still have to bent over the spay nozzle is rubbish difficult to adjust if at all expensive for what it is only thing I can say it does kill the weeds very small ones just showing kills within a few hours larger say several inches takes towards a week
Cheaper than other Retailers
This refill round up works out cheaper for me. I have claimed some waste ground to turn it into a wildlife corridor as people cannot get behind us as it is well secure and since cleaning out the burn Otters are using it for a short cut to the river. I use the round up on the over grown banks makes it easier to cut with the strimmer. Always recommend Round Up good value for money 5L Refill, will continue to buy from the seller as it stays at this price beats everyone else prices.
took a few doses but worked
I had a number of weeds on the driveway.
I applied 3 doses of this over a week and by the end of the second week the weeds are dead.
I’d hoped it would work more quickly with a single dose… I’ll try it on some others and see how it compares
update: I’ve found this to be far more effective on dry (and especially sunny) days, in which case a single squirt seems to take down small weeds within 24-48 hours
Good produc
I bought this to kill weeds on my driveway and stoned area, one spray and the weeds were dead and brown within a few days.
I used the refill to top up an existing pump and spray bottle, taking off the lid was a nightmare (I thought I was going to snap something), and I question how much plastic is being saved with this refill bottle.
