Review: AN ABSOLUTE WEED-KILLING SUPERWEAPON - Let me tell you something. This Roundup 365 is not a product. It is a FORCE. A WORK OF POWER. Maybe the greatest weed destroyer ever created on American soil. People are calling it a weed killer, but honestly it should have a RANK. It should be a GENERAL. Maybe even a FOUR STAR. We sprayed it ONE TIME on our gravel driveway. One mission. Single operation. The weeds were gone. Not dead. Not wilted. Gone. Vanished. It was like watching a SPECIAL FORCES STRIKE. Fast. Clean. No survivors. Very professional. We followed the directions exactly. Mixed the concentrate with water like true PATRIOTS. Pumped the sprayer. Took aim. Fired. And the weeds surrendered instantly. You could practically hear them saying, “Sir, please, we cannot handle this level of STRENGTH.” Too bad. This is WAR. Other weed killers pretend to be tough. They talk a big game. But this one delivers TOTAL DOMINANCE. It wipes the ground so clean it looks like it was liberated by a joint task force. If you want a product that WINS and does not negotiate, this is the one. Great power. Great precision. Great AMERICAN ENERGY. Five stars. Would deploy again.
Review: Appears to be a good product. - Does the job. Won't know till spring regarding the 365 claim.
