Used this spray on Friday & it's now Sunday & I can't see any difference with my weeds. Only picked this product because it said 1 hr. action. As i'm a pensioner I choose carefully, but not this time apparently. It was on special at Woolworths for $8.90 but i'm writing this off as a loss. I don't usually complain about things but found this to be very misleading.

The label says to expect visible results in one hour, except in heavy shade. 24 hrs later, various types of weeds in full sun actually seem to look healthier than before the spray.
