Solar Sound & Light Alarm Motion Sensor 110 Decibels Siren Sound Alert & 6LEDs Flash Warning Strobe Security Alarm System for Farm Villa(1 Pack)

Poorly translated instruction (Chinese to English) but easy enough to figure out.The alarm is "Drive your neighbors crazy" loud, so beware. I use this to deter a pesky bear and the flashing light is sufficient. If you are concerned about break-ins by people, this alarm With the flashing light will do the trick

It works well and it's very loud lol

Good Device, works well ... I own 6 of these and will buy more. Several have been functional for 2+ years.However, Due to the extreme amount of filth in the air from pollution, chem-trails, dust/dirt.... the photo electric cells become covered in a haze of pollution and stop generation a charge to recharge the battery.I have solved this by placing 3x layers of Kitchen Plastic wrap over the photo cell and tape them into place. I replace them as needed.

It was not as loud as previous purchases. I used to hear it from inside the house now I don’t wish you could adjust the sound to make it louder

If you’re in need of a very loud siren, this is not a good purchase. It accidentally went off around my VERY nervous dog. She didn’t even jump or get scared. The volume of the siren was disappointing! Since I only needed it for the siren, I didn’t bother checking the flashing light mode.

This is the second similar style of these motion sensor solar/usb rechargeable alarms I use around my vehicle. I like this one a bit better because it has a longer detection range, housing is a clear red, the red led's are quite bright and you can see a very good battery inside not the usual cylindrical type, flat not replaceable. Since I don't need it during the day it's set for nights only and since there's no remote I wondered how I could shut it off fast. In this mode the solar panel acts as a switch, shine a bright light on it and it thinks it's daytime and shuts alarm off. Otherwise it will sound for 45 seconds and will repeat if motion is still sensed. The remote for other alarm always needs fresh battery, acts up if remote sensor has moisture on it, so 6 of one half a dozen of the other. I rely on these alarms along with 3 driveway motion sensors placed strategically using different tones for each. A good little alarm, enough to send any human vermin away asap, easy to set just one button to push and if there's no sun just plug in the usb cable it charges up fast.

Used this tent camping to keep coyotes&mtn lions away, I do carry a firearm however early warning or deterrent from having to use it is a plus!! It worked great as it scared a pack of 3-4 coyotes away on our last night. Has really good range and goes off well before they get too close. It scared them when it went off and they turned and halled ass away from our campsite!! Is a must on every camping trip going forward for us because we have a 2yr old daughter, and it definitely helps to prevent possible issues with early warning and prevention of a dangerous interaction!! Definitely recommend!!! Also very easy to use, and set up! We set it for night time only with flashing light and alarm. You can set it and forget it.. when sun goes down it arms and when sun comes up, it disarms. You can also set it to be on 24/7 and it’s solar charged so it doesn’t die!! Can set to have flashing light only or flashing light with alarm.. your choice!! Very very much worth the price, might even be under priced!!! Didn’t have one issue using it zip tied to tent poles in the middle of Steady 20-30mph wind and dust in the middle of the Mohave desert for 4 days straight!!! Look no further... this is a definite hidden value on Amazon!!

Gave it 2 stars becasue one stopped working already.....Nice Lights , i hope the other one continues to work i bought 2 .I guess that's why they are pretty cheap compared to others ,
