    Simple, effective water alarm
  

*by F***H on Reviewed in the United States on July 29, 2015*

Very compact and simple water alarm. We put it in our hi-rise's air conditioning closet to alert us if the condensate drain is leaking, a common problem in older buildings. Several units and hallways have been damaged due to this, and even a device that automatically shuts off the water supply main will not prevent A/C water damage, as it is a separate system. We placed the main unit just behind the return air vent so it is completely invisible but very audible. We figure if we're home and the alarm goes off we can take care of it, and if we're gone, our security system picks up the audio alarm and will alert us as a "loud noise" alarm and we can have building maintenance take care of it. Sensitivity is good, we tested it with a slight amount of water under the A/C unit and confirmed that the alarm was loud enough for the security microphone to detect. Nice product..

    DO NOT BUY! Unit lasted 8 months and now I can't contact the company for their lifetime warranty.
  

*by M***Y on Reviewed in the United States on July 15, 2018*

This unit didn't last 8 months. And the 3-year battery life only lasted 4 months. I replaced their generic battery with a fresh name brand battery, but alas, it only lasted 4 months as well. After placing the 3rd battery in this unit in an 8 month period, I heard static coming from the speaker so I tested it by placing metal across the contacts to make it alarm, but it wouldn't alarm. So no problem, this unit comes with a FULL Lifetime 100% Satisfaction Guarantee! I quickly sent an email off to the company for information on how to return it, uh-oh, another problem. My email cannot be delivered because there was a problem with the recipient's email system. Now what? Buyer beware, not a reputable company to do business with. Amazon should drop them for not honouring their word.
