Review: It's a good product! I like it! - It's a good product! I like it!
Review: And the cap fits the old RoundUp perfectly - So I decided to buy this refill bottle due to it's amazing value for money and thankfully I could change beautifully the old cap with the large wand we have inherited from the previous home owner, including her weeds she never bothered to get rid of. Some hard worked money saved there. Churchill would be pleased with me: take care of pennies, pounds will take care of themselves, right? Maybe the previous gallon was old as it did not work much, yes, even chemicals have a warranty, and I am hoping this new gallon to do it's magic. In interim, I also purchased a Hand weeder tool on this site where I do 99% of my shopping, and I removed all the weeds beautifully around our Koi carp pond as I do not want to upset them with un-necessary chemicals. Robins still comb our grounds besides all the other cardinals, golden finches etc coming here for the seeds and nuts we buy for them - so I will probably have to use this solution only before sunset not to upset them either. Love nature and wildlife

### ⭐⭐⭐⭐⭐ Still the Gold Standard in Weed Killer
*by S***K on March 12, 2024*

I've been using Roundup for 20 years for my parents as well as my house. It's been the most consistent reliable chemical for weed killing - I would strongly recommend getting a general pump sprayer as the ones Roundup sells just doesn't have enough pressure especially for bigger weeds. I bought a cheap pump sprayer from Home depot and use it with this refill - It lasts me about a year before I need to get another refill. I have a 7500 Sq lot in SoCal so we do get a lot of weeds and with the rain lately, it's been more heavier than normal. Roundup remains my go to for weedkiller and I would encourage you to use the same if you haven't already!
