Security for Our Lake House Sinks
[This review was collected as part of a promotion.] I love our lake house but struggle to keep informed about the uptake when at our primary residence 3 hours away. After several water leaks. I noticed this gadget in the store. It was super easy to install. Download the app, make sure your wi-fi is on 2.4 mg not 5mg. The install literally takes seconds. I used the foam stick up adhesive vs screws. Makes me so happy to know I will be notified if there's a water issue.

      Awesome water leak sensor
      [This review was collected as part of a promotion.] This energizer water leak sensor is awesome. it is simple to use and the free app for your phone is great. The setup is as easy as following a few steps in the instructions. When setting up the WiFi, I did have an issue, but the directions included a second option for setup. I set the device up in less than 5 minutes. I am using as an alarm for if my sump pump fails. It comes with an adhesive strip for placement, and it has a battery indicator in the app that notifies you when it is low. Overall great product!

        Lasted just 4 months. WiFi connection stopped. Unable to regain it. Bought 2, waste of money. Do yourself a favor and pass on these.
          Died after a few months
          Save your money. Dropped WiFi connection and unable to regain a connection. Like most brands of these things, they don’t last very long.

            Small yet powerful
            [This review was collected as part of a promotion.] There couldn't have been a more perfect time for me to get this. We had a slow leak under the bathroom sink but couldn't catch it leaking. I got the Energizer Connect Smart Water Leak Sensor and hooked it up to my phone and were able to tell immediately where it was. I've never gotten to try a product like this before and Energizer delivers.

              Peace of mind
              [This review was collected as part of a promotion.] We have this sensor set up for our kitchen sink which tends to leak and we don't realize it until we pull something out from under the sink. The sensor was easy to install. Since installing it, we have not experienced any problems, but I just feel better knowing that if and when it DOES happen, we will know immediately!

                Works as advertised
                [This review was collected as part of a promotion.] I got this as a gift a few weeks back and didn't know what to expect. Well I hooked it up under my kitchen sink in the cabinet as a precaution. To my surprise it , the alarm sounded within about a week, looked under the sink and indeed it was wet from a leak. I was able to fix leak with no damage done. Without sensor I would not have found leak for awhile with lasting damage. Highly recommended

                  It’s ok
                  [This review was collected as part of a promotion.] It took me awhile to figure it out. I have had no water leaks so I can’t tell if it really works or not. I guess it would be more for someone who has water leaks often maybe. Otherwise I really like the idea of this.
