I bought these out of desperation. I spray the plants with smelly deer repellent, but if it rains or I don't keep up with it, Bambi and crew are most pleased to eat everything in the space of a night or two. I have spent quite a bit of money on landscaping and I don't care to have it regarded as a free salad bar. So.....what to do?

I had my doubts these blinkers would really work, but I thought nothing ventured, nothing learned. Well, I'll be damned. Since placing these in my yard 2 months ago every night, I haven't had one single thing eaten or even nibbled on. I followed the advice I read online and placed one in one specific area where all the hostas are and the other in another area where they like to eat things. The trick is to constantly rotate these around your yard, but always within eyesight of where the deer will potentially try to eat your plants. I have placed nails in various tree trunks around my yard about 4' high, so the blinkers are never in the same place too frequently. Another thing I do is take these into the garage and super charge them under a light that stays on all day. They hold a charge and blink for 11+ hours. I gave my parents a set and they have had the same wonderful results....not one hosta touched.

And I'll say this. I went out into the yard on a dark night to see the full effect and the creep factor is excellent. I can see why the deer don't like these. They look like red eyes watching. The blinking makes them even creepier.

I'd 110% recommend these. These are sooooo worth it and I can finally wake up each morning and enjoy my hostas.....with the leaves still on them!!! Hope I don't jinx myself by writing this reveiw!!

Update...I didn't jinx myself and these kept right on blinking through one of the worst night time thunderstorms you can imagine.
Update #2....I did not put these out one night because of a bad hurricane that came through. I figured the deer wouldn't be out in that kind of weather. Guess again...no blinkers out, so they ate several hostas. Sneaky, smart little buggers!

I have previously purchased these products before. They work very well. They keep predators away from your livestock at night. A really good buy. My last batch that I purchased lasted 5 years outside in all types of weather.

The deer have knocked down the fencing, too many times to list. Trying to keep them out of the orchard and eating all of the pears, peaches and apples, these have worked far beyond my expectation. Who knew?

We have ordered and used these devices for several years and have found them very effective in keeping coyotes and other predators away from our property and our outside pets. In addition, they have the added benefit of looking like surveillance cameras!

Red LED will blink all night. Have not had predators near chickens since installing.
