Qualirey 4 Pcs Solar Alarm Motion Detector with Sound Outdoor Motion Sensor 129db Barking Dog Strobe Light Gunshot Sound Alarm Detector Noise Maker Warning Lamp for Home Villa Yard Farm

This thing does what I was looking for. The batteries last forever. It chased away animals for the first couple of days. Any movement triggers it. The problem I am facing is some very smart squirrels. They figured out what this is and they just just slowly tiptoe around it to avoid triggering it. The groundhog just ignores it. The sound it creates is loud but they don't startle the animals anymore. Hopefully, they'll keep the deers away.

I did not like the instructions they don't tell you how to set up the modes. Other than that they function well but it takes hours to figure the modes out and then you can't figure them out you have to go by trial and error. Very annoying to neighbors who have to put up with the noise while you're trying to figure out the mode.

Good value and seems to work well at keeping wildlife out of gardens. There’s not much for instruction but once I got it set on infrared sensor they are working very good.

Suggest not using them if you have close neighbors. In the country is good because there isn't a volume control. It is loud and annoying which is perfect to keep critters away.

This is the second set I bought. I have them everywhere in my yard. Around my gardens and most importantly near my garbage can. I watched a bear approach and when the alarm sounded he ran away and has not been in my garbage since!! The deer get used to it if it’s in 1 place for too long so I move them around.

bought on July 2nd, now august 18th all 4 have stopped working. 2 still will flash slight some times. in my book waste of money ,

I can’t charge it on rainy days because it makes noise inside house that scares my cats.

Works
