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 Now I have a friend for Life Spring has arrived, the grass and weeds were happily growing larger and larger in my rather big parking area. As I walked around inspecting it,I was certain they were laughing knowing they were way ahead of me and had me beaten!! Not yet,I had a plan,I had purchased Dura Zone concentrate. I emerged sprayer in hand and I sensed they still felt they were indestructible ,,,,, Until they got there first taste of Dura Zone. I am now the Master of my grass and weed free parking area,. Thank You Dura Zone!!!

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 2 out of 5 by from Needed a better sprayer Bought this a couple of years ago. While the product itself was very good, the sprayer container was a complete disaster, simply would not hold pressure to effectively spray. They must have gotten a ton of complaints and looks like they changed sprayer container. Amazing how they didn't test it first before putting it out there. But it least they finally changed the container. If the new container works better it should be an excellent product.
