    JOHN K. -- eau claire, WI   10/17/2013
    Fast delivery and item as described. (Price best I found and about 1/3 of what the alarm company was asking!)
    HEE LAI -- kuala lumpur, Malaysia   5/2/2013
    Both are reliable product and works well.
    HKG -- pensacola, FL   4/16/2013
    The WaterBug is an excellant product. I have a sensor under every sink, every toilet, the dishwasher, the refridgerator,and the washing machine. I installed after line to sink failed and caused major home damage. Units have been installed for 1.5 years. I test on a regular basis and work perfectly. No issues; very easy to install. I also installed on/off switch to the DC power source so I could shut off water when leaving home for an extended period. Excellant product that is fairly priced; a real bargin when compared to coompetetion.

    These do what they are supposed to, but they could use a longer hookup wire

    performed as stated
    NEIL -- phoenixville, PA   9/1/2004
    works well as described. Very happy with this unit! My refrigerator is very close to the floor and this unit is too thick to fit underneath in the back. Therefore my refrigerator sticks out from the wall a bit to make room for this device to fit on the floor behind it. I wish it wasn't quite as bulky for this particular location.
    HERMANN -- elma, MB   6/18/2004
    Best surface sensor available!
    DAVID -- southfield, MI   10/17/2003
    These are really high quality and perform very well. Great product!
