Best i found so far
Works great. Very pricey though. Mostly cause at the ratio needed vs what they suggest is not even close. Double it for sure, unless you aren't using for weeds and just grass. Grass dies very easily and fast.

Works well
I first bought the Ace Hardware brand. It did not work well even after several applications. Then I tried this Ortho spray. The weeds are dead.

Be patient. It will kill everything
Edit. I wrote my initial review about a week after applying it. However, after waiting over two weeks, it’s obvious that this stuff doesn’t work. It’s been about three weeks now in the areas I applied to are completely destroyed, which is great. But I don’t know how long it will last. But overall pretty happy with the product at this point. Original post. I applied this over a week ago. The areas have only mildly started to die. Most of the areas show zero indication of dying. This is in sharp contrast to RoundUp. Which shows sign of dying the next day and completely dead in a week. Would NOT recommend This is incredibly frustrating

Worth the money!
This is the only vegetation killer I use - on multiple properties. It is very concentrated, so a bottle goes a long way. It works as it should, I only use it once a year in last spring and have no issues with regrowth, controls weeds and keeps them out of my landscape rock. It works fast - weeds are dead within 24 hours.

Great for weeds… not good for grass you want to get rid of
This works well in weeds… but does not clear the rogue Bermuda grass. Whether it lasts six months as it says is still yet to be reviewed.

True to the end
This item proved itself, best I've ever used, true to the end, used 1st day results the very next, shrunk and conquered the many ground weeds from the rain...extremely happy will always keep on hand..
