ChunHee Solar Sound & Light Alarm Outdoor Motion Sensor 129db Siren Sound Alert & 6LEDs Flash Warning Security Alarm System for Villa, Farm, Chicken Coop,Yard, Garden

Really works! Charges by day with solar, scares foxes away at night, just the right sensitivity

works great, scares off my pesky neighbor

I deleted one star because of two items. First, the instructions do not explain how you switch modes. There is a button on the back that apparently does this. Second, includes screws to install on a wood fence or tree but I have a chain link fence to which to attach. I had to devise a way to do this and still make it easy to remove to charge especially in winter when not enough sunlight to power most outside solar items. That said the unit looks good. I have yet to test so if come up with issues in use will come back to edit this review.

Pretty good it takes a little time to figure out the settings. Good motion detection and alarming

I bought these same ones 2 years ago and they were perfect. I bought some last year as a back up and finally had to use them. They are ridiculous. The alarms go off under every condition.. Too cold, too hot, too windy, it’s Wednesday, ……. etc. Not sure what happened to these but the are useless and provide false alarm’s constantly. Buying back ups is a really dumb strategy as return policies will leave you “holding the bag”.

These motion detector units work great in activating the flashing red lights and the alarm sound. The alarm sounds for 45 seconds which is a long time but you do want it to be effective in keeping rodents, animals and people away. There are five mode settings and when it is on the first mode to deactivate the unit you just press the black button on the back side four times to turn it off. If the unit is still active then you may need to repeat pressing the black button four times again and you do this quickly. You do this quickly to not disturb other campers at a campground. When at a campsite that is close to the road where vehicles may be coming by frequently it does sound on, so I recommend to wait until later in the night to set out around your vehicle and or camper trailer. Where I was staying recently I waited until like 10:00 or later to set the units out. Once again the alarm sounds for 45 seconds so it may seem like it is not going to stop but it will stop sounding. I highly recommend this product.

I kept these up all winter and they still work. I need about 10 more for around the garden and to give as gifts to people I know who also have deer issues. They are loud if you are outside, but if your in the house, they are hard to hear, so I think they would be OK if you live in a place with neighbors close by. Just tonight one went off and I heard it because the door was open. I got up right away and couldn't see anything with the flashlight but eyes glowing out in the woods, many yards from the alarm. Get enough so you can place them 20 feet apart all around the entire garden. They would probably scare the crap out of a burgler.

I have problems with rabbits, chipmunks, squirrels, raccoons and opossums eating my flowers and vegetables and they also raid my bird feeders. I thought these might help but the sound was very loud and annoying and of course went off constantly, and I’m not sure it helped. Didn’t use them very long.
