Rated 3.0 out of 5 by 2 reviewers.
Rated 1.0 out of 5.0 by Manufacturer has changed this model The manufacturer made am important change to this water heater timer which, in my view, makes it an inferior choice. The over-ride switch which allows you to turn it on or off, as in a breaker, is not accessable from the exterior of the unit. This is a critical feature. The other dismay was the timer gears and the pins for selecting usaged. This is not a heavy duty clock by far. I would not recomend this product. I returned it unused to the store and bought an intermatic brand timer. This is a safety issue that should be addressed. February 3, 2015
