    5.0 out of 5 stars Absolute money saver!

    This device has saved me over hundreds, if not thousands, of dollars! I placed this near the overflow valve on my water heater to detect any possible leaks down the road. Well not even a year later the sensor went off and sure enough the water heater had started leaking and failing. Had it not been for this device, it may have been hours before we noticed the leak was occurring given the location of our water heater! Instead this device notified us within minutes of the leak occurring so we could take measures to shut off the water supply to the water heater before it flooded our home.

    If you have any possible area in your home where water leaks could occur, I highly recommend you get this device. You honestly owe it to yourself to buy this! Literally saved us so much money and headaches!

    It connects easily to an existing Ring security system, it’s very small in size and appearance allowing it to be tucked away unobtrusively anywhere in the home. The coverage and range is excellent for the location we had installed this device. The speed of alerts is near instantaneous once water is picked up by the sensor. Overall the performance is excellent, and this was amazing value for the price we paid!

    5.0 out of 5 stars Easy Installation and Peace of Mind
    Reviewed in the United States on April 17, 2024
    I recently installed the Ring Flood Alarm Sensor in my home and I couldn't be happier with the results. The installation process was incredibly easy and straightforward, taking me just a few minutes to have it up and running. All I had to do was place the sensor in the desired location, connect it to my Ring Alarm system, and I was good to go.

    The sensor provides me with a sense of peace of mind knowing that my home is protected from potential flooding. The moment water is detected, I receive an immediate alert on my phone, allowing me to take action quickly and prevent any further damage. This has been incredibly helpful during heavy rainstorms or when I'm away from home for an extended period of time.

    I also appreciate the reliability of the Ring Flood Alarm Sensor. It has never failed to detect water when present, and the battery life has been exceptional. The sensor is also durable and well-made, so I have confidence that it will continue to work efficiently for years to come.

    4.0 out of 5 stars Ease of use

    So far, I have no issues. Easy to set up an easy to use. The only thing I wish we could see the current temperature and see the set points for the alarm.

    This is one of those products you hope works as it is designed but in an ideal world, you never know. I had this behind my washing machine and this promptly notified me when I had a leak. Saved me a bunch of time and water damage. Worked as advertised. Bought several more as a result.

    5.0 out of 5 stars Just saved us from having a major flood in our house!!
    Reviewed in the United States on August 4, 2022
    We purchased this for our second home in Florida so that we would be alerted if there was a water leak in the house. We have one located in each bathroom, under the kitchen sink, and the laundry room. I thought my husband was being a little over paranoid, but boy was he right. We are actually here in Florida now luckily because last night at 12 am my husband heard the "Water Detected" alarm going off from our Ring Alarm. He jumped out of bed and ran to the laundry room first, nothing there. Then off to the second bathroom to find water coming out from under the wall next to the sink. He was able to quickly turn off the main water shut off outside and stop the water. At this point it only took 3 towels to mop up the water. Since my husband is handy, the next morning he opened up the wall behind the sink to find out that a water connection had completely failed and water was shooting out into the wall cavity. The sensor had luckily went off right away so we were able to shut the water off almost immediately. If we had not had this we would not have known about the leak until the morning and our whole house would have been flooded as this bathroom was on the other side of our house. My husband was able to fix the failed connection (I told you he was handy!) and problem was solved in half a day, with very little expense on our part. I cannot recommend this product enough. Thank god we were here and not back in Seattle, but if we were we would still have been able to contact our house watch services and they could have come out and shut the water off and minimize the damages. Such a small investment saved us possibly thousands of dollars. We do not have flood insurance here in Florida due to the extremely high cost, so any damages would have been on us.

    I have 4 of these throughout my basement. I bought these about 2 years ago and have had 2 incidents that these helped me with which saved me thousands of dollars in potential damage. If you're on the fence about buying these just buy them before it's too late.

    Pros:
    - Easy installation (About 1 minute to configure with the app)
    - Replaceable batteries
    - App is very intuitive
    - App customizations allow you to change notifications per sensor.

    Cons:
    NONE
