This device works basically as advertised; however, make sure what it does is what you really need before purchasing it.

I bought it to monitor an electrical circuit with a trip-prone GFCI safety device. One outlet on the circuit powers a chest freezer out in my garage. I plugged this unit into an indoor outlet connected to the same circuit. If the GFCI trips, cutting off the power to the freezer and creating a nightmare if the situation remains undetected, the alarm goes off inside.

In my case, this works out perfectly. When triggered, the alarm is just loud enough to attract attention.

There are two significant "catches." First, and as others have noted, the alarm is not very loud. It is about as loud as the beeps of a small alarm clock, or perhaps the more powerful alarm watches. You can hear it fine in a nearby quiet area. You can't hear it through moderately thick walls or from very far away. I can hear it OK inside my single-story house, but I couldn't hear it when I tried connecting it in the garage.

Second, while the unit is fairly unobtrusive, it does tie up an outlet without providing a pass-through socket, and it may interfere with plugging something into the adjoining socket. This could be a problem if you need the socket it occupies, or if you are trying to connect a transformer brick, GFCI plug, or similar bulky plug-in into the remaining socket of a typical outlet.

If these two issues aren't a problem, then this device will do the job just fine.

I bought this hoping it would warn us of a power failure on the circuit to our chest freezer. The light is cute, but the so-called alarm buzzer of 85 dB is a joke. it may be 85 dB if you place it right next to your ear, but from a distance of 20 feet, it is barely audible. to make matters worse, our unit broke in less than 3 weeks. I would not recommend this to anyone; I wish the star ratings allowed an entry of zero stars

This alarm is a must for anyone with a CPAP machine. It is small and unobtrusive. I no longer am concerned about a power outage. If the power goes off in that outlet, an alarm goes off similar to an alarm clock. There is also a light that goes on at the same time. This is a must for anyone that sleeps with any electrical appliance. Great peace of mind for a small price!

This works as it should, except that the description said it has a very loud alarm. In fact, it is a very quiet alarm (about the same volume as a small, battery-operated travel alarm clock). This would probably be fine if you plan to use it in a room that you are in. But I wanted something that will be installed outside the house, and still audible inside. It's too quiet for that.
Otherwise, it is a good unit.

Box say 86db, I can't believe it is more than 8.6db. This is junk and I feel as if I was ripped off.

This product works as intended. When the power went off, the light came on and the alarm sounded. The alarm is not very loud, about the same as an alarm clock.

This "alarm" is too quiet. It wouldn't wake up a mouse. It measures 56db @ 12" from the device.
For comparison, the fan on the freezer I wanted to protect is 54db.
It needs to be at least as loud as a cell phone.
Useless for me.

I don't feel that the device performs as advertised. The alarm was said to emit an alarm sound of 86 DB, if I recall correctly. The alarm sound could barely be heard across the room and information I read concerning sound levels said that a sound level of 86 DB would damage your hearing if exposed for a long period. I wanted to use the alarm to alert me If I lost power to my freezer in the garage and this unit certainly would not do that. I returned the unit.

This product performed as advertised during a recent power outage. As others have stated, the alarm is not very loud. The volume is similar to an alarm clock and worked for us, but it probably would not be heard in a remote location of your house, e.g. garage or cellar. It does meet our needs though.

The alarm is not much louder than a wrist watch. (or a VERY soft alarm clock) If you need this to wake you... you better be a very light sleeper.

Packaging says it is 86 dB loud. I found a hearing site online that says prolonged exposure to 85 dB would casue hearing damage....and a lawn mower is 90 dB. I seriously, seriously doubt this product is anywhere near 86dB

The light portion of this item is good!
