Pros
  • It takes two AAA batteries. Most of the other units take 9V batteries, which are super expensive. AAA batteries are 20 cents each on Amazon.
  • Very easy install. Literally just apply the double-sided tape (included) and stick where you want it.
  • Super loud alarm. Crazy loud. You wont miss hearing this. You cant be in the same room when this is going off, its so loud.
  • Two alarm volume settings. I left it at the loudest, but seriously, youll probably be just fine with the lower volume setting.
Cons
  • Very short sensor cord. You just have to mount this lower, I guess
  • It isnt clear how to best position the sensor. It seems like youd want the metal pieces on the sensor to touch the bottom of the cabinet to catch those slow leads, but Ive no idea how to do that. Right now Im just leaving the sensor laying on the bottom of the cabinet under the pipes.
