Customers say

Customers like the basic leak detection of the product. They say the sensors pick up even a drop of water. However, some customers have reported issues with appearance and connectivity. They mention that the app is very glitchy and hard to get them to connect. They also have problems pairing the unit to their WiFi and that the device loses connection to the internet. Customers also have issues with battery life. Opinions are mixed on quality, app, ease of setup, and water resistance.

AI-generated from the text of customer reviews

47 customers mention36 positive11 negative

Customers like the leak detection of the alarm. For example, they say the basic detection works well, the sensors are well-integrated with the shut-off valve, and they pick up even a drop of water. The notification of a wet sensor worked well. Overall, most are satisfied with the product's leak detection capabilities.

"...I'm very impressed!! The sensors pick up even a drop of water...." Read more

"...Eventually it worked.Pros- Compact water leak sensor that can be placed directly on the surface, or connected to a remote sensor..." Read more

282 customers mention131 positive151 negative

Customers are mixed about the quality of the alarm. Some mention that it works well, is easy to use, and runs without any problems. However, others say that the alarm is not loud enough, the protective shield doesn't work, and the battery lasted for less than 6 months.

"...Otherwise, it's an excellent product! It still works well and does the job even when not stuck to the wall so it deserves 5 stars...." Read more

Customers are mixed about the ease of setup. Some mention that it's fairly easy to set up, and the installation of the sensor is not technically difficult. However, others say that the install directions aren't much help, the instructions are small, and confusing.

"...I've had these for several months so far. They were very easy to install and easy to set up with wifi. They never seem to go offline either...." Read more

"...appear to be working fine, but I was really unimpressed with the setup process that kept failing. Eventually it worked.Pros-..." Read more

"...That’s my experience. These Moen installed easily, as my 2.4 wifi worked well with them...." Read more

"...The connection process for me was very successful on all three of the sensors. I like the fact that alerts are sent to your phone...." Read more

59 customers mention21 positive38 negative

Customers are mixed about the app. Some say that it is good, comprehensive, and easy to setup. They also say that the Moen app is rock solid. However, some customers have reported issues with the app being wonky, glitchy, and unfriendly.

"Their app is a little wonky during setup. I had to reset the unit a couple of times and start over to get through the process...." Read more

"...And it worked flawlessly by sending an alert. I also liked the app very much. Gives you the temp and humidity...." Read more

"...With the battery almost dead, the unit gets hung up while trying to connect to internet...." Read more

"...First of all, you need a completely different app for this (the "Flo" app vs. the "Moen" app), and the Flo app feels like it was written by amateurs...." Read more

41 customers mention15 positive26 negative

Customers are mixed about the water resistance of the alarm. Some mention it's very sensitive to moisture, and it detected a trace of water. They like that the main sensor stays away from water and the cord just hangs down. However, others say that one of the units would not detect water, the sensor cable appears to only detect water if the logo side is down, and the water shut off had been shut off.

"...installation I received an alert of a critical issue and the water had been shut off. Since work was 40 minutes away, I waited until I got home...." Read more

"...I really like that the main sensor stays away from water and the cord just hangs down...." Read more

"...One of the units would not detect water...." Read more

"...After the detector puck has been submerged in water, it takes a while to dry out completely...." Read more

154 customers mention15 positive139 negative

Customers are dissatisfied with the battery life of the alarm. They mention that the included battery only lasts a few months, and the supposed two-year lithium battery life isn't accurate. The battery retention is tricky, and it may report confusing battery life initially.

"...I easily installed all 12 Moen units. One did come with a dead battery...." Read more

"I love these devices but I hate the cost cutting of batteries only. In theory, you put these were water can leak but you would not notice in time...." Read more

"...to make the electric connection were so far apart that the battery was loose inside? If these are hand inserted, how does this not get noticed?..." Read more

"...When the unit arrived the battery was loose and the insulating strip was separate in the case...." Read more

151 customers mention15 positive136 negative

Customers are dissatisfied with the connectivity of the alarm. They mention that it fails to connect to their home network, has problems pairing the unit to WiFi, and has trouble retaining connection to the internet. Some say that the phone won't pair and that the device does not reconnect within 24 hours.

"...Ideally, it is better on AC. If you lose power, the device cannot talk to the wifi so the only reason for the batteries is bottom line cost and..." Read more

"...batteries before you install them, mine were at 64%, 47% and too low to even connect to...." Read more

"...At the end of the set up it wanted me to link to Alexa which I don't have...." Read more

"...from the unit, you won't hear the alarm. I also had problems pairing the unit to my WiFi...." Read more

34 customers mention8 positive26 negative

Customers are dissatisfied with the appearance of the alarm. They mention that it's very glitchy, and difficult to connect a new device to the app. They also encounter errors at various steps of the process. Customers also say that the alarm is pretty buggy and hard to get it to connect. They configure the device using the weak UI and receive terrible error messages. The procedure failed many times before it succeeded, and the unit is probably defective.

"...There is a spot to link it up within the app, but errors out (flo error 009) Also the alarm is not loud enough to install in your basement...." Read more

"...took at least 8-12 minutes per sensor (not a "few minutes) this step is glitchy, the app freezes and I hard to restart this on 3 sensors...." Read more

"...I am giving three stars because the unit is probably defective or became defective after the update." Read more

"...The app seems well designed...." Read more

Seems like a good idea to install this as an alert in case there is water intrusion.
5 Stars
Seems like a good idea to install this as an alert in case there is water intrusion.
When I read the reviews some seem to have trouble connecting the wi-fi. The connection process for me was very successful on all three of the sensors. I like the fact that alerts are sent to your phone. I actually put some water by the sensor to test it and it worked perfectly.
Thank you for your feedback

5.0 out of 5 stars Water Leak Detection Hero
Reviewed in Canada on June 14, 2022
Used in the water leak subsystem of my home automation system. Tried several commercial water leak detection products but all came with a discrete sensor that only detects a leak if placed in a depression under the source. This sensor cord is so much better as it is 6 feet in length and can be connected in a chain of up to 3. It can detect water leaks along its whole length. Uses. Standard 3.5 mm connection. I have this connected via low voltage wiring to an ESP32 microcontroller that can handle 5 of these detector cords For most non-diy people, I would suggest replacing the discrete sensor that comes with most leak detection products with this cord sensor. Those discrete sensors are not very useful where you are not able to place them in sump directly under your washing machine for example. They are likely to miss small leaks but would work well if a pipe burst...
