Hoont Cat Repellent- Squirrel Deterrent

This is one of the worst pieces of product garbage I've ever had the displeasure of dealing with. Seemed like such a good idea too, and with decent reviews I was very hopeful. Well, actually if you do the math on the reviews, it seems as though roughly 1 in 10 units don't perform and I guess this was my unlucky day. I hate spending time on a lengthy review but to save some of my fellow Amozonians from some headaches and frustration I feel it's my duty to go into some detail. And maybe even the manufacturer will take note although I doubt it. I can tell from their weak website and "instruction slip" that consumer communication is not their forte. So here goes: Easy to assemble, yes. But from there it goes downhill fast. Instead of providing easy to see visual instructions, there's a pithy slip of paper with not well-written instructions, at least one of which makes absolutely no sense: "The jet spray repeller's coverage area is arc shaped. Set the width of this arc by sliding the two prong clips to the left or right." Seems clear except there are not two prong clips that you can adjust into any kind of variable arc, only narrow and almost 360º. But that's minor stuff, on to the real failure: IT DOESN'T WORK! How does it not work? Let me count the ways. It behaves randomly every time you make make a slight adjustment like the distance or go into the battery compartment. Starting with brand new batteries, the unit wouldn't come on at all even after adjusting the on/off distance dial. Then finally it came on and wouldn't turn off! So I turned the dial to off and then it wouldn't come on again at all. Maybe something wrong with the batteries? So I swap fresh batteries and try again. Okay now it's working, great. But then I go to adjust the distance and it stops working again! I'll give it a rest, maybe it needs time to adjust (?). An hour or so later it's working again but now it's going off every 30 seconds while there's complete stillness in the area! And it won't stop! For the next several hours, repeat and rinse (which is what will happen to you as you adjust and try to get it to work). Nuff said? I hope so. Avoid it. Unless you love frustration.
