What Customers Are Saying
Customers overwhelmingly praise this weed killer for its rapid, powerful action—killing weeds and grass within hours or days, even stubborn varieties, by targeting roots completely. Many highlight the 12-month prevention barrier as a standout feature, particularly for driveways and patios. The Comfort Wand design is consistently noted as easy to use without special tools. While a few report the prevention claim didn't last or experienced limited effectiveness, and some mention concerns about cost, the vast majority consider it a reliable, long-lasting solution worth using.

I HATE weeds that pop up in cracks and crevices in my driveway, sidewalk, front entry, etc.. My sidewalk is smooth concrete but my driveway, front entry and patios are medium size gravel rock and using a shovel or a crevice weed puller makes the job so much harder. So I needed something to get to the weed root and kill it fast. I sprayed Roundup just as the sun was setting one night and by the next morning, the weeds were already starting to turn yellow. By the time I got home from work, they we...

So far it is good. Hope it is all it claims
I used the sprayer from the original purchases on the refill. It worked, but not as tight as on the original. But it worked. It is taking alot of the product to kill the weeds on top of the rock lawn that has been neglected for a few years. There is some sort of vine all over the back rock lawn and very hare to kill. I do not know how effective this will be over the next several months much less 12 months, but here we go to find out. After shoulder surgery, I cannot dig through rock.

Higher cost, but at what cost?
It does kill weeds, but it seems it's no more effective than other versions of this brand. We will see in a year if what's dead stays dead. It's not universally effective, I sprayed my pebbled walkway (following instructions) and there are still living plants a little over a week's application. I look forward to trying another sweep this weekend before adding additional stones.

Roundup 365
I know this product and others like it have had many controversies, but I have used this for years. I particularly like the fact that it is a once and done product and saves lots of time in lawn care for me. I am in my 70's and shortcuts are necessary when you can't get down to weed. I highly recommend. As a precaution I always wear a mask and gloves when applying any type of product like this.

Lasts longer then 12 months
Used this product two years ago. Kept the weeds away in all that time. Just now noticed some weeds coming back. With my advanced age 84 years old, so thankful it lasted for more then 12 months. We live in a heavy overgrowth of blackberry bushes. It’s worked in the past very well, so it’s time for another application.

Great long lasting killer
This stuff works and last long however not as long as advertised. I usually do 2-3 applications a year which is still better than the regular stuff that requires bi-monthly application

Great buy for the money
Used beside our front sidewalk and killed everything. We will have to see if it works for a full year.
