This lets you know when you have a leak
Everyone needs this in their home. Bought two. One for house and one for Beach condo. Never know when you may have a leak. Rather catch it when it happens than spend thousands in water damage after the damage is already done. We have recommended them to others in our Condos

Performs as advertised
As advertised. Sensed and alerted when water contacted probe. Options for both audible alarm and notification on iPhone via SwitchBot app; both of which worked as expected.

Detects water when it touchs the sensor
Let's you know if there is water leaking. Or in my case if the sump pump stops working. Has a alarm and can see on my cell phone.

Good value for leak detection
Great product. Easy to setup and add to my network. Works as advertised and uses very little battery power. Easy to install. Overall a great value for the price. Would recommend and buy again.

I’m so glad I found what these sensors I didn’t know they existed!
These sensors are worth their weight in gold! They warn you before there’s a flood!

So far okay!
So far it works well. When I tested it the alarm sound was moderate, but the notifications were in real time. I didn't give it 5 stars because mine came without a user manual and the already installed batteries were low. The website does not offer a manual that I could print off or instructions. The app was slow and tedious when trying to add the device. I had a power outage a couple of weeks ago and my base flooded twice. Once after my secondary sump pump battery ran out then after my generator died. A leak detector that doesn't need AC power is critical for me.
