BLACK+DECKER Solar Jet Sprayer

First things first, everything you read in the negative reviews is true. I've gone through two sets of these, I'm finally on my last one and when it fails (it will, trust me), that's it for me, Black and Decker. First, they don't always sense animals but are excellent at picking up wind motion. We have a serious feral cat problem (cats have more rights in Hawaii than homeowners, that's another tail, no pun intended). We've done everything we can think of to deter these felines who have literally destroyed our yard. First, you're constantly adjusting the batteries since when the sprinkler does finally activate, it jiggles the batteries and won't activate, what a pain. Then, they leak incessantly, no matter what you do, plumbers tape, etc. And the hoses, we've gone through many to correct the issue, even high quality hoses don't attach properly to these units. Lastly, the flimsy plastic they're made of. The units are good for about four months, then they go bad and stop working completely. One neighbor recommended the Orbit 62100 Yard Enforcer. They're not solar powered like the B&D's, but since the B&Ds are such a cheaply made product, the Orbit is by far more worth the investment and extra $$, simply because they are far better, mostly metal made units and last with no hassle set-up. They also don't leak incessantly like the B&Ds. I'd give these a zero as well if Amazon would let me, once you're outside their 30 day return window, you're sunk. DON'T WASTE YOUR TIME, MONEY OR HOURS OF EFFORT ON THESE UNITS.
