### ⭐⭐⭐⭐⭐ Works as described.

Been working without issue for over a year.

### ⭐⭐⭐⭐⭐ Warning system of failure
*by T***M on January 4, 2026*

Basement lift station warning for failure. We hope we never have to hear it as it fails. But just in case.

### ⭐⭐⭐⭐⭐ Its loud
*by E***H on May 10, 2016*

Worked perfect for my liberty pump pro 380 sewage simplex system. This model of alarm is for indoor use only. I would recommend getting the alarm float pre-installed if you are buying a liberty simplex system. Its easy to do but pretty nasty if the unit has been used. The 9 volt battery backup is a nice touch.
