Works exactly as we hoped.
We often purchase this product. It can cover large areas covered with weeds - it can effectively remove the weeds and the effect is rapid, without affecting other plants.

Works as advertised
People this product works great. I sprayed in my flower bed and it started raining in next 30 minutes unexpectedly. I figured what I sprayed would wash away. I came back out the next day and the weeds were already dead.

Turn an overwhelming yard into a beautiful one
My yard had an overwhelming amount of weeds. Instructions for how to use were the most difficult part of this. Instruction book ripped on both sides upon trying to remove - seems like they could just be printed on the bottle instead of including a peel off book. Results not seen within 6 hours as stated but definitely within12. Easy to use with the continuous sprayer. Some of my bigger weeds will need an additional application but I am happy with the results.

Rain came early, but RoundUp still came through
I applied Roundup 365 to a gravel walkway that had been overrun with weeds. About an hour later, the skies opened up with unexpected rain, and I thought for sure I’d have to start all over again. But nope — this stuff still worked. Within a few days, the weeds were shriveled up and dying off exactly as promised. It’s been several weeks now, and nothing has come back. Not even a hint of green. I’m seriously impressed by how long-lasting and effective it is, even with less-than-perfect conditions. Pros: ✔️ Kills weeds fast ✔️ Lasts a long time ✔️ Rain an hour later didn’t ruin it ✔️ Great for driveways, walkways, and fence lines Cons: ❌ None so far — just make sure you apply carefully and avoid any plants you don’t want dead Definitely a repeat purchase. If you're serious about keeping weeds away for good, this is your product.

Useless weed killer
Not sure how this can be Amazon’s choice? It’s the first weed killer I’ve seen which does absolutely nothing to the weed, not even the slightest discoloring of the weed. DO NOT BUY this one.
