Yardeen Outdoor Solar Repellent for Yard Motion Activated Water Spray Garden Sprinkler Irrigation System

I have had all brands of this, and this one is also good. I tightened everything, during assembly, put batteries in, but did NOT secure the battery cover with the teeny screws, details after. Adjusted the direction and boom, off we go. Works very very well, sensitive! Just what I want for those nasty neighbors with dogs, kids, squirrels, and old women who like to climb up and try to take cuttings of my plants. Only thing I hate: the battery cover. Love where the compartment is, no need to take unit out of ground when putting in new batteries, HOWEVER, the cover is so secure and deep, the screws are not needed, and what is gawd awful, the cover is extremely hard to take off! There is no lip, and you need a fine thin knife to squeeze into the side of it to uplift it. Poor design there. So this is why as a whole, I did not add the teeny screws to further aggravate the issue of the cover.

I use them to keep bear's away from my back porch and garage, they go by motion sensor and the sprinkler comes on and scares bear's, cat's dogs and other animals from the area you don't want them. I definitely recommend this product!!
