Roundup is the best for killing weeds outright, but, do not spray flowers or grass.

Better than other products in the same range and the packaging is very easy to operate

Round up definitely does the job, but the trigger on the sprayer broke half way through using the bottle.Recommend roundup, but not this applicator.

Kills small weeds straight away, though need to be used a few times for tougher larger weeds
It was great to use. Not having to mix any harsh chemicals.....already done. Convienent bottle and sprayer to use. Can get straight into the job with no mucking around.
The active ingredient in Roundup causes cancer according to the WHO. Why are people still buying this weedkiller with that risk?
I thought this sprayer would be easy to use, but I ended up cutting it open and pouring it into my usual sprayer.
Most ideal product & packaging.
Round up is normally great, but these spray bottles are rubbish. They don't spray properly at all.
Amazing stuff. Kills the weeds and so easy to use. Definitely recommend it.
