Review DuraZone
Rated 5 out of 5 by from So you have a rock parking lot you say? This parking lot too often looks like a lawn, a really rebellious lawn. It takes a man-sized quantity of a man-sized product to bring weeds and grasses to heel. Bayer Advanced™ DuraZone® 1.3 Gallon Ready-To-Use fills the bill, and empties the lot.

Rated 5 out of 5 by from Easy and effective I love this! I have 2 houses that have long concrete driveways and brick patios along with many flower beds. I used to fight the weeds all summer long but with this product, I can just walk along and spray and I am done for the season! I used to bend down and have to spray every weed but this takes me about 10 minutes compared to 2 hours and it keeps weeds gone the entire season. This is truly a miracle for me as it frees up my summer to do things other than yardwork! Thanks Bayer!

Rated 5 out of 5 by from Twice dead I tried Bayer DuraZone when it was on sale at my local home improvement store. It had generous amounts of same ingredients plus more as the then leading brand. Now I will always use DuraZone. It kills and keeps on killing. I use it twice a year for total ground control. It completely kills the weeds and grass on contact and then it kills again for many months.

Rated 3 out of 5 by from Poor Sprayer We got the Ergo Sprayer version. Really good sprayer. EXCEPT! It only lasted for about 1/4 of the 1.3 Gal bottle and then the Switch ceased to function. Couldn't fix it, so now have to pour into another bottle to use. Disappointing feature. Solution works GREAT on unwanted plants, but the Ergo Sprayer is a BIG DISAPPOINTMENT in its duration.
