Review on 💧 Flood Buzz Water Leak Detector - Pack of 6 by John Wood

I love the devices and have ordered 2 sets of 3 each. All but one of the units work correctly by reading the test instructions and 1 unit does not work even when placed in a bowl of water, all 5 others are currently in use and I am very pleased to have this 'extra' alarm system is under control. especially mussels. Disappointed that 1 unit is defective and didn't feel the need to return all 6 units to replace 1 unit. So keep all others as directed in usage. I will not return for a 1 unit replacement.
