It certainly does the job in alerting you to a power outage, but the alarm is very loud and annoying. My only suggestion would be to have a setting where you can just have just the red light flashing during a power outage and not listen to that alarm, or have a volume control for the alarm.

Great price. The product is a little loud. I think that is the point, but I would have appreciated a simple volume control even if it were a potentiometer screw sticking out somewhere. I would like to know that the power went out without being jolted out of my computer chair. Maybe I can make a muffler for it. it would also be nice to have a suppression button for the alarm so that the device can remain active for the next outage but the alert can be acknowledged and then disabled. Currently I believe the only way to disable the alert is to turn it completely off with the side switch and when the power is restored the device remains off. Its a useful alarm at a good price.

I live in a rural location that loses power often, especially during very cold winter nights during snowstorms. One night, the power went out and my home temperature dropped to 45 degrees before I woke up and started the generator. I immediately bought one of these alarms. It works well and it's very loud. It will wake you up even if you sleep with earplugs. Just test it out periodically to ensure the batteries and on switch are functioning.

The battery compartment does not have the normal protections to ensure that a 9 V battery is inserted with the correct polarity. There’s a reason that all devices that use 9 V batteries have the kind of connectors they do because this device has no way to force the user to connect the polarity correctly, it is very likely that a battery could be inserted backwardsBecause this is designed to be plugged into a power outlet, and usually one that is not frequently, it is very easy for someone to put the battery in the wrong direction, plug it in and forget about it. If this were to happen, the battery would overheat, possibly create a short or explode, and possibly even start a fire, which would be devastating to anyone this happened to.This device is EXTREMELY dangerous.

Overall: Bought his about two months ago and I'm very happy with it. We have a family member who uses CPAP and my wife has been worried about a power failure occurring during the night. This alarm will allow the user to wake up and plug into a battery back up.Pro's: Does exactly what it says it's going to do.Con's: As others have said, the instructions could be better, but it's easy to use and spending a few minutes with it will tell you more than the instructions ever will.Other reviewers have mentioned the lack of features. This is true, but this was only a $10 unit. Premium features come with a price tag. For this price point, this is a perfect product.I recommend this product.

We have a photovoltaic system with battery backup on our house. But the batteries can only power the essential items in our house for a limited amount of time. A lot of our essential circuits have other items plugged in, and we need to marshal the amount of power usage to insure we don't run out of battery power. We put this alarm on one of the outlets that does not receive power from our battery backup, since the batteries take over seamlessly during an outage.There is a red flashing light, which is quite bright, and a VERY loud alarm that goes off when the outlet looses power. This lets us cut off not essential items, check the amount of juice we have in the batteries so we can manage our use. It is a great tool for people with systems like ours.
