  • Don't consider any other leak detector over this one!
Style: ‎2.4 GHz Wi-Fi Connection via Base Station Color: 3 Water Detectors & 1 Base Station
I can't begin to tell you the stress I have over leak detectors. I bought a D-LINK several years ago that was impossible to set up and as of 2023, the company decided that they weren't going to support the product anymore. This left countless owners out in the cold with an app that no longer supported their detector. So, I had to consider finding a new leak detector system. And, let me tell you, it wasn't an easy task. I poured through more than a dozen such detectors on Amazon reading reviews that didn't convince me there was any reliable enough system worth investing my money in... ...that is until I came to X-Sense. There were some very encouraging Amazon reviews touting this as the best product of its kind with ease of setup and exceptional performance for indicating water leakage. Let me tell you, this product exceeded ALL expectations. To begin with, I was fearing the setup process knowing what I had gone through when I set up my D-LINK. Shortly after purchase, the manufacturer sent me an email with a link to an online doc with what I am assuming was an updated installation guide. This was something I very much appreciated as it showed that the manufacturer was still taking an interest in making certain that its customers had a favorable installation experience. And get this...installation took under 7 minutes and it was completely effortless and flawless. The big thing to keep in mind when installing is that this won't connect to a 5GHz network, which is what most home routers are outputting. To get around this, all you need to do is create a guest network that generally broadcasts in the preferred 2.5 GHz band that this device needs to connect to. I started with the base installation and which took less than a minute to complete. You simply download the X-Sense app and it walks you through the process. After that, adding any one of the 3 satellite leak detectors takes even less time. You push a button and it connects to the base station. We have a very large home and I was very happy to see that the signal range in which the base and satellites communicate with each other is pretty immense. There has been no problem with a signal loss between devices. Once everything was connected I did a quick test where I placed one of the satellite detectors in my sink and ran a small stream of water. As soon as the water hit the sensors on the bottom of the detector, a loud alarm on the base station went off and a notification was sent to my iPhone. WOW! Could it be THIS EASY? I have never seen something like this come together so easily. It was so effortless to set this up. What you get in the box are one base station and 3 satellite detectors. You also get a power cord and brick for the base station. I would advise centralizing the base location in your home. The app is very good with one major annoyance that has been talked about in other reviews here. The plus is that the app is well laid out and easy to use. It offers a terrific one-glance look at your activated system, its online status, and battery levels. And speaking of batteries, they are easily replaceable. On the downside, I wish the developer would update the app so users are not annoyed by the advertisement to purchase extra protection. It's fine to read about it once, but I shouldn't have annoying reminders pop up when using the app. It's really ruining a perfect experience. Perhaps in an update, the software developer can fix this. Other than that, I am just ecstatic about this purchase. I still can't believe it took mere minutes to set everything up without any of the errors and hassles one expects from these products. If you are looking for the perfect leak detector system, I can't fathom you can do any better than this at the approx. $50 price point. ... show more

  • Simple to setup and very effective
Style: ‎2.4 GHz Wi-Fi Connection via Base Station Color: 3 Water Detectors & 1 Base Station
This set of water leak sensors is a joy to setup. Everything just works. The provided hub sends out timely notification of any leak detected. I tested this set extensively before deciding to review it. It’s been very reliable through multiple water seepage into our basement due to unusually heavy rains. I placed them sequentially toward the high point of our basement. This way I can tell how far the water has intruded before I need to be concerned. The built in alarm is effective and the volume is adjustable in the well-designed app. ... show more

  • Very nice and easy to setup
Style: ‎2.4 GHz Wi-Fi Connection via Base Station Color: 3 Water Detectors & 1 Base Station
I had a water leak a few months ago that ended up costing me $350 to replace some flooring. These could have saved me that money and the time to replace it. They are very easy to setup and the app on the phone works well. I tested each of the sensor and they work with no issue and sound an alarm almost instantaneously. Well worth the money. ... show more

  • Works Decent But…
Style: Accessory for SWS54 kit Color: 1 Water Detector
This Product is great and does work well enough to pay for itself. I installed the base station and a total of 6 water leak sensors. The set-up is easy and not difficult to understand at all; however, I find while setup is easy, connection to the Wi-Fi is only 2.4ghz like most IoT devices. The main problem with today's IoT Devices and not all of them are up to date with the WiFi Security standards the base station only allow 2.4ghz on WPA2 or WPA 2/3 and it doesn’t allow Protected management frames. For the WiFi I believe the base station has a security weakness. The Water leak sensors pair fast and easy and are very sensitive, we discovered a sink under our kitchen sink the first day of install. Both the base station and sensor alert making it known a leak has been detected, additionally they can be silenced as well. The App controls are easy to use and firmware updates are possible. The sound control on the basestation is limited but making adjustments using App allows for sound changes. ... show more

  • Peace of mind at a decent price
Style: ‎2.4 GHz Wi-Fi Connection via Base Station Color: 3 Water Detectors & 1 Base Station
Easy to configure and seem to work well. I placed one next to my sump pit and accidently splashed it with water when emptying my dehumidifier into the pit. Nice and loud from both the sensor and the "hub" and the alerts worked well.

  • Easy to Set Up and Monitor
Style: ‎2.4 GHz Wi-Fi Connection via Base Station Color: 3 Water Detectors & 1 Base Station
These monitors and the main unit are very solid feeling and were easy to set up. After setting up you use your phone to run a test sequence to make sure the unit will warn you with a beeper and also on your cell. I got the original 3 with the base unit and purchased and additional 5 to monitor several locations in my home. I really like these so far but ultimately we will have to see if they do well when an actual water event happens. Good price for what you get. I didn't rate the battery life because I've only had them in use a couple weeks so I have no idea. ... show more
