Fast Action Weedkiller Pump 'N Go Spray – 5L Ready-to-Use Glyphosate Formula – Kills Weeds & Roots with Visible Results in 1-2 Days – Refillable Pressure Sprayer with Extendable Lance

Very simple to use, to be honest with you, and it's a very big tub of weed killer. It seems to work as well. I've sprayed once outside, and the regrowth has been a lot slower than what it was without using it. I think it needs a little bit of persistence, and you've probably got to use it several times for it to completely kill them off, but I have noticed a big difference.

Been using this for years and never let us down, easy to use, very effective and low odour and does what it says on the tin.

I recently used the Roundup Total Weed Killer Pressure Sprayer and overall I’d give it a solid 4 stars. It does exactly what it promises—kills weeds effectively and fairly quickly. Within a few days, I could already see noticeable results, especially on common garden weeds like dandelions and nettles. The pressure sprayer is a big plus. It’s convenient, easy to pump, and gives a consistent spray, which makes covering larger areas much quicker than using a manual trigger bottle. I also appreciated that it comes pre-mixed, so there’s no hassle with measuring or mixing chemicals. That said, it’s not perfect. The sprayer can feel a bit flimsy at times, and I found that it needed occasional re-pressurizing more often than expected. Also, while it works well on most weeds, tougher or more established ones may need a second application. Overall, it’s a reliable and time-saving product that makes weed control straightforward. With a slightly sturdier build, it would easily be a 5-star item.

Reel good stuff kills all sorts of weeds fast

I’ve tried quite a few weed killers, and this is one of the more effective ones I’ve used — especially if you want something ready-to-use that actually kills weeds at the root, not just the surface. The Pump ‘N Go design is a big win for convenience. There’s no mixing or measuring — just pump and spray. Once pressurised, it delivers a steady, even spray which makes it easy to cover patios, edges, and larger areas without constantly stopping or tiring your hand. What stood out most is how it performs over time. This is clearly a strong formula — weeds don’t just wilt, they continue to die off over several days and visibly shrink. I saw results within a couple of days, and it kept working well beyond that. I’ve uploaded photos from days 3, 4, 6 and 16 to show the progression. It also held up after some light rain shortly after application, which I wasn’t expecting, but it didn’t seem to affect the overall effectiveness. The smell is noticeable while spraying but not overpowering, and it fades fairly quickly once dry. In terms of safety, this isn’t something you’d want pets around while it’s still wet due to the strength of the ingredients. I kept pets completely away until it had fully dried, and I’d recommend doing the same. One thing to be aware of — I did feel slight dizziness while spraying, so it’s worth using this in a well-ventilated outdoor space and considering a mask or face covering if you’re sensitive to sprays. Pros: ✔ Ready-to-use — no mixing needed ✔ Even, consistent spray from the pump system ✔ Covers larger areas easily ✔ Starts working within days ✔ Continues killing weeds over time (not just surface-level) ✔ Still effective even after light rain Cons: ✖ Slight chemical smell during use ✖ Can cause dizziness if inhaled — take precautions ✖ Needs to fully dry before pets can access the area ✖ Initial pumping takes a bit of effort Overall: If you want a no-fuss weed killer that actually tackles weeds at the root and keeps working over time, this is a solid choice. Just use it with basic precautions, and it delivers exactly what you’d expect — even with a bit of unpredictable weather.

It got rid of some of the weeds but not as good as I hoped …… what really works and is chemical free is pouring boiling hot water from your kettle slowly on the weeds …. Now that really does work 🥰

Purchased to use on driveway block paving, were pesky weeds, etc pop up. Very easy to put together and use, it appears to be working very well. I like the fact I can purchase refills, which can be attached to the original fittings. Will purchase again if the need occurs.

I ordered this thinking Amazon would be cheaper but today in tescos the same size exactly with spray was just £12’99 should of gone to Tescos not going to rate product because it does a good job! **** I’ve had it before ***this is an edit I apologise for this review because in going back into Tesco again to day I noticed there was a 3lt ! pack as well on the day I was there the 5lt pack must of been in the wrong shelf in front of the 3lt hence my review there 5lt is £29. So is more expensive than Amazon so sorry but just had to snd say ,!
