Tripped by Very Thin Layer of Water, Even R/O Water,
Verified Purchase(What is this?)
This review is from: Water Leak Alarm
On more than one occasion I have half flooded the kitchen whilst filling bottles with Reverse Osmosis water. This alarm is set off by just a very small puddle of water, in spite of the water being very pure. The alarm is loud enough to be heard around the house without waking the dead.
