Most Helpful Review
"I got this for a friend who had a water inlet valve problem on her washer. If we had this little $5 unit in place, there would've been less flooding on her laundry room floor. I like that this comes with everything you need except a 9v battery. It has double stick tape for the control unit and the sensor. You get a pack of 3 for around $15. Cheap insurance! I tested it by putting the sensor under the kitchen faucet. Wow! It's Loud! A nice feature is that it has an on/off switch. Not sure why you'd need it because you'll always want it 'on', but that's handy. I guess if it's going off, you don't want it screaming at you while you mop up the water. This is good for any type of water / liquid overflow. It could be the laundry room, under sink pipes, whatever you can imagine. The cord to the sensor seems long enough. You could always splice more cord into it to make it longer and I'll bet it will work just fine. I was glad to find these in a 3 pack even though I only needed 1. I'm sure you'll come up with other places where a water / liquid sensor could be useful."

Inexpensive insurance to detect water leaks and prevent damage. Will install when we go full-time.

The Topvico Water Leak Sensor Detector Flood Alarm works exactly as described. What I received was fully functional, and the cost was excellent for what you get. The build quality is on par with the price, and the size is perfect for placing in tight spaces.
