Don't buy refund still outstanding £100
They do not understand a word of English ,I feel I have been transported to a hawkers stall in my home country. I had to call call to get a refund Products are equally unreliable as the people behind it. Quick money

Drill holes to find water
I brought this for my daughter and her husband who had a water leak from somewhere. I thought they would hold it against the wall and it say when it found it. The end has to come into contact with water so you have to drill holes into the wall so you can put the sensor into it to touch the water. They said it was helpful but it wasn’t what I thought it was going to do.

Very much recommended!
This is only one of the line of YoLink products that we purchased and all of them are very reliable, easy to operate and recommended! This one I'm using as alert for sump pump. Hi availability, long range coverage and reliability. Various scenarios can be programmed and alarms will be received. Shareable monitoring.

Water leak sensor 2 works great for tight spaces
I mostly used the water leak sensor 1 in my home, but I could not get it to fit behind the fridge. The water leak sensor 2 fit perfectly behind the fridge. I tested the sensor by exposing it to a tiny amount of water, and immediately I was alerted. The sensitivity is amazing.

Easy Set Up and Reliable
Easy set up and stays online unlike my previous Flo sensors. The leak detection is VERY sensitive. It detected a small amount of rain that was coming in by the water heater vent, wasn’t causing a problem but previous sensors didn’t catch. It’s takes awhile for the sensor cord to dry so it can be reconnected. We just got an extra cord to plug in while it’s drying.

Great product
Yolink is an awesome smart home product that I have bought lots of. Works when wifi goes out, uses hardly any battery power and never have false alerts. Will be buying more Yolink products in the future as I build my smart home. You can trust this product.
