Briidea Power Failure Alarm with LED Indicator & 80dB Siren, Powered by Rechargeable Battery (Included), Perfect for Monitoring Refrigerators, Freezers, Sump Pumps, Aquariums

Works well for me. Not too loud, not too soft. We're just a few rooms away. A basement may need a louder product.

I use this on a dehumidifier I have in my crawlspace. In testing I found I could not be too close to the unit when it went off as the siren is VERY loud! Seems to "work" well. I would recommend this one or something similar for the situation.

Works as it should. First time plugging in there is a clicking sound. When clicking stops you can test it thenFound in other reviews that is normal. It indicates it is charging its battery. It comes as quality one. Two are pictured in listing but you get one.

I bought this Briidea Power Failure Alarm for my minifridge, and it didn't work out of the box. Every time I plug it into any outlet or even an extension cord it makes a loud nonstop clicking noise while the green light is on. According to the description, it should just show a steady green light during normal power, and only switch to a red light with a loud siren when the power goes out. Mine never stops clicking and never behaves the way it is described. It is basically unusable. If I unplug it for a couple minutes and plug it back in it seems to stop the noise but only temporarily. The noise comes back in about 30-60 seconds which you can see from the video. I recorded a video (attached) to show exactly what it is doing and it is clear this is not normal/expected behavior. I also emailed Briidea support ([email protected]) about the issue and they seem to be ignoring my email. No reply, no help, nothing. So I ended up with a broken product and no customer support. I would not buy this again and I would be very careful trusting this company or any of their products to protect anything important.

It works exactly as it says. It already saved me a ton of money when the breaker tripped for my basement freezer. The alarm went off as expected.

Our garage freezer is on a GFI circuit and it “popped” recently and we didn’t notice it for a few days, so almost everything was ruined. This gadget screams annoyingly loud if the freezer (or whatever) loses power. I’ve tested it and it works great.

Power goes out and this screeches. Works great. Saves a fridge and freezer full of food in the garage. Everyone should have one.

Works great loud enough to hear upstairs from basement. Simple design doesn’t leave much room for error.

Works great!

Appareil très efficace le son n’est pas trop fort,et ça fonctionne à merveille

Doesn’t work, makes an annoying sound when plugged in.
