Query: Good, loud, but not perfect.

This alarm works well and I am generally happy with it. It's extremely loud and should work well for basement or garage applications. If I have any gripes, it would be that the cord could be longer and, more importantly, that it would be nice to have an alarm silence function. The button on the front of the unit only serves as an alarm test button and the only way to silence the alarm is to remove the sensor from the liquid. Also, changing the battery requires a screwdriver.
