Ardwolf Early Warning Water Sensor/Alarm

We need 150 alarms for our condominium. We bought and tried five different brands. All were tested a half-dozen times (connecting the contacts with a moist finger) and all sounded each time, with this one among the loudest. Then all were gently placed in water deep enough to make them float. This was still sounding 24 hours later. BUT we could not open the case to replace the battery. It is supposed to be pried open, but the two halves were assembled very tightly and we couldn't get a screw driver or sharpened end putty knife in between to pry them apart. The sleek round shape is difficult to hold firmly when trying to do that. The pry device could easily slip and gouge the hand holding the alarm.

I have it on the normal ding ding noise. All the other noises sound like old flip phone ringtones. I thought it'd be different dinging noises but I guess since it's electric they took advantage of doing something different. It's decently loud. I put it at the back of the house where my birds are so if it rings my birds go nuts and add to it.

Out of the box installation. Purchased for the laundry room and the overflo pan of the air-condition units in the attic.

Love the options for sound. Good volume choices as well. Easy to set up.

I have this on a shaded porch so I am assuming it does not need much sunlight to work. The chime on the inside is loud and clear. I have had many compliments. Such a great product for the price.

It blew us away with the cool sounds when we first set it up. Easy setup, lots of cool noises, lights up when it dings, etc. Now we're impressing our guests. "Where did you get that?!" Is a common question.

I have purchased numerous moisture alarms. This one is poorly built compared to others I've bought. Mine doesn't work if you set it right down on some water. Spend a couple more bucks and get something better.

Works well! Would order again!
