Arrived quickly, looks good quality. Nice rising and falling siren pitch means thet its unlikely to go unheard. Working well as an overflow level alarm in a water tank.

Very loud alarm a bit flimsy but does the job ideal for under washing machine early warning of leaks etc,I put mine under bath as I have a new build famous for leaks.

Bought 2 of these as alarms for antique toilet cisterns. Both tested OK, so ideal for the purpose. Good loud alarm - really spooked the tom-cat. The only instructions were in Chinese which required scanning and translating. The gist of these was not to get the battery container wet, switch off before fitting battery, fit battery the right way round, wipe sensor dry after alarm triggered, don't expose to heat. My only niggle is that the switch on/off markings are white-on-white and difficult to read. Really good value for money.

After flooding my Aquarium room by leaving the tap on and forgetting it when filling the water mixing butt I bought this, It would waken the dead, all I need to do now is remember to fit the sensor before I start.
