Review: Works as advertised. - Fair price too. I purchased these to replace an other 15 year old brand. Place them by my washer and near my water heater.
Review: Small expense, huge savings - These are great. They work as advertised. I put one on the floor in my water utility closet with water heater, reverse osmosis filters, water softener and whole house water filter. Five days later I heard the alarm, It's loud. I checked the closet and sure enough the drain line for the softener system had split. I was very glad that I was able to catch it early and repair the line. Well worth the expense. Recommended.

### ⭐⭐⭐⭐ Solid, cheap, practical drip detector for under six dollars. But screwing them on is a bit much.
*by N***B on November 7, 2025*

It works. This unit went off at 2am and saved us a chunk o money in flood avoided. Solid, cheap, practical drip detector for under six dollars. But screwing them on is a bit much. Old school analog. Obviously, if you are (a) not at home and (b) cannot hear them --- they are useless. So (a) Get the smart units that send a message to your phone if you are away from home a lot. Next -- and this is important--- it is true as a couple reviewers have noted, the loudness of the alarm is (weirdly) impacted by how you screw the lid on. See pics. Basically, there is a vented 'hole' in the top of the unit. You want that hole clear (you should see a gold tone plate at the bottom) for the sound to emerge vehemently. Otherwise, the alarm is absolutely muffled and remarkably less loud. The problem is there are no markers to help you adjust your 'screw' to make sure the hole lines up with an open space underneath. If you only turn far enough to land the vented hole over something solid (like the battery) you lose, I'd say, about 30db in loudness. It's pretty annoying actually. So we gave up after screwing/re-screwing the first lid on about twenty times trying to get it just right. Eventually, we settled for most units just-sort-kinda right. See pic (pinkie is pointing towards the "open" correct orientation; the other is blocked and alarm is softer sounding). Picture of the single unit shows the gold tone plate underneath that you DO want to be able to see. Problem is... we only got one perfectly aligned like this. :-( Annoying.
