Title: Only used one time but...
Review: After dusk it made things way too dark to see anything. During the day, anything light colored looks like a ball. But having said that, I think if it was a bright day and you had just green grass and a ball, it would be easier to find. When I went there were leaves on the ground. So I guess under ideal circumstances it might help you. In other cases, you might be better off without them. Will keep trying them and see how it goes. I only used them one day so far.
