Great results, good value.

Works as well as any of the more expensive brands I have used in the past.

Works just like the name brand weed killer!

So far so good. This is comparable to the big name brand weed killers. Decided to try it because of the price and the many good reviews.

Work effectively and have no odor.

[This review was collected as part of a promotion.] Ive tried this once in my back yard, it take few days to see the result but work well, there is no scent or odor. I'm about to try with my front yard. I would say this weed killer is value for the money.
