4.0 out of 5 stars It works great, but should be louder for garage use.
By FYX193 on December 11, 2019
I purchased this product to act as a deterrant and notification to family/friends that accidentally unplug the extension cord powering the deep freezer. I have lost a freezer full of food two separate times because of this problem.

After testing it plugged into a surge protector to cut power with the switch, the alarm is very obvious if you are in the same room or if the door is open, but less noticable if you are in another room next to the room where the alarm is wth the doors shut. I don't have a dedicated power outlet that is near the freezer, so I use an extension cord with multiple outlets. The alarm is plugged into one outlet of the extension cord and the deep freezer is plugged into another outlet next to the alarm. I have this setup in my garage about 15 feet away from the interior door to the garage. With the door shut, i can barely hear the alarm sound when I am 10 feet away on the other side of the door. In my opinion if the alarm was louder than 100 dB it would be much better. 78 dB is just a little to low for my purpose. I would like to clearly hear the alarm at least half way across my house with it setup in the garage.

If you have this setup inside your house, like in the kitchen or an interior room, then I am sure it would be more than acceptable. The garage door is typically metal insulated or a solid wood door. The garage also has insulated walls and this helps insulate sound more than an interior wall or door.

I also suggest this company make a smart version of this unit that includes the alarm and also sends push notifications to email or an app. That way I can be aware if power is cut away from home or in the event that I cannot hear the alarm when I am at home.

Reviewed in Mexico on November 14, 2020
Quedó perfecto para mi necesidad, que me avisara cuando se fuera la energía eléctrica por las noches para mi máquina generadora de oxígeno sin que me diera un infarto por el ruido y este aparato lo logro perfectamente! Es excelente para una casa habitacion. Es pequeño, practico y se ve de calidad, conectado en México a 110 o 127 V. Si lo necesitas en un taller o fábrica donde hay mucho ruido no te sirve.
