Thank you, SimpliSafe, for delivering a product that exceeds expectations!

These small water sensors connect quickly and seamlessly to your Simplisafe base station. It literally takes mere seconds to connect and you can customize the name on each one to help with identifying the cause of any possible leak. I have a large home and have multiple sensors on every level and in every area of the home. Even the sensors located far from both the WiFi router and base station stay connected. I also appreciate the small size so they are quite inconspicuous. They are only about 2 and 1/2 “ in diameter.

I tried out the water sensor by pouring water on the floor and having it flow into its path. The sensor was triggered instantly and we also received a call from Simplisafe with 30 secs of the sensor going off. I was pleasantly surprised and glad to have these under the dish washer and washing machine.

Super easy to install - just place it where needed to alarm for water leaks. I placed it in the laundry room next to the washer.

I am throughly aggravated at Best Buy. I purchased these on March 4 and have been out of town for a few weeks. When I get back to install them, it's obvious that they have been an open box and they are not sealed. The plastic tab to remove to activate the batteries are not there so clearly a return - yet Best Buy sold two of these as new even though they were open box returns and NOT sealed. I DO expect to see my review made public or I will file a complaint with CFPB.

As a homeowner, one of my fears is water leaks. I have had 1 water leak that cost me thousands and took months to completely repair. So when I chose SimpliSafe as my home security system, offering a water sensor for such an inexpensive price was one of the deciding factors. Installing the water sensor is about as easy as it can get. Go to the control pad, select "Add a new device", remove the battery slip and push the button on the sensor. Once it registers (only a few seconds), you can name it and then place it on the floor where you want protection. How does it work? Well, a spilled cup of water in our kitchen immediately set off the water sensor, but mopping the floors and hitting the sensor does not. This is a good thing because an overactive sensor is useless because you can never tell if it is a real alarm. I currently have 4 water sensors installed and have 3 more to add to completely cover my home. The first three have been in the system for about 6 months. The SimpliSafe water sensor is inexpensive compared to other options and works like a charm.

I bought this to place near my air conditioning unit to detect possible water leaks, and it has been working really well so far. Setup was quick and easy, and it gives me peace of mind knowing I’ll be alerted if any moisture or leaks appear. It feels reliable and does exactly what it’s supposed to do. I definitely recommend it if you want to help prevent water damage at home

This Simplisafe water sensor is very easy to install and seamlessly integrates into your existing Simplisafe system. It has great water sensitivity, and its size make it a great and necessary addition for all spaces you want to protect from water damage in your home: under the sinks, attics, utility and laundry rooms...

These sensors are small enough to fit in tight spaces and being wireless are super easy to move. They don't stick down or attach to anything, just set it where you're concerned about water. Because they are often buried behind things maintaining a connect far from the base could be an issue. I have one that has lost connection a couple times but then finds it again in less than a minute. Great piece of mind.

Easy to install and detects small amounts of water

Replaced a bad water softener, and added this device just in case. Great price, and Easy to install. Just pull out the battery tab and hit button, system recognizes it and simply add it to your security system. No worries if I have a leak or a complete water line breakage simpli-safe will notify me. Silly not to have it.

While we were vacant from our home, a pipe overflowed in the garage, leaking onto a brand new wall we just had built. We were able to get to it and take care of it right away because of SimpliSafe notice.

Super easy setup. Small profile device that detects the smallest water leak. Very good deal, have installed multiple around the house.

Best alarm system on the market. Simple set-up, highly responsive support, reliable sensors.

Great little sensors!! As with the entire system, they are easy to set up. Be careful when you are initially setting them up. They are VERY sensitive and after they are set up in the system they can easily trigger an alarm from the moisture in your skin. So once set up, don't touch the contact points on the bottom. Better to put in place and then set up.

this product will prevent major water damage, it is sensitive and alerts you to water on your floor, I have had water splash on it and it definitely works

We will see. Haven’t had a leak yet so I don’t know if they work. However, it was just as easy as the other devices to set up. I think it is extremely important to have water detectors as I have had $200,000 worth of damage in the past due to a leaking fitting, and I had a leaking water heater once that was caught with a leak detector. I have leak detectors (some zircon) at my homes. Worth the peace of mind.

super easy to set up, works great. Easy to connect to my existing simplisafe setup with easy integration into my app/settings. Better price than buying directly from simplisafe too. i have several of these and have helped me identify water issues in a vacation home that i otherwise would have missed

Ive tested it and it works , I hope I never need it to work for real. I have a simpli safe system and I am very happy with their product. I don't expect this add on to be any different.

I bought this for incase my pipes burst, or my water heater started leaking. I was skeptical about it working at first, but I will say it definitely does work. I decided to test it with a cup of water after I connected it to my system. I thought I had put my system in test mode, but quickly found out I hadn't when the monitoring service started calling me as soon as the device triggered. Simply dry the underside of the device very good, and it's ready to use again and again. I feel better knowing I have a better chance at stopping the water damage if something happens, before it gets way too costly.
