I've been a Revain customer for quite some time now and rarely get a bad review but that was bad for me. I purchased this item brand new in January 2016 (photo included) for a critical drain pump in my basement during record-breaking California rainy season. I tested the device a few times initially and it seemed to work fine, plugged it in and forgot it until the end of the rainy season. In the spring I turned it off. However, when I plugged it back in later that year (November 2017), I tested it and it didn't work. That means the "AC present" indicator was on when it was plugged in, but there was no alarm when it was turned on and disconnected from the new battery. The same applies when you press the "Test" button, there is no sound. I tried a different battery just to be safe but that turned out to be correct, the bad circuit alarm didn't go off, pardon the pun. I'm not sure at what point it failed, but in any case the fact that the 'AC present' light was on without one being able to know that the alarm had failed is worrying. The worst part is that the two week return period clearly passed and the manufacturer refused to honor the product warranty even if it failed within a year. 12/15/17 Response from the manufacturer (CSH Inc.) who sent me a new implement. With this in mind, the above circumstances of a bad device can be reconsidered by those who want to give this product a chance. I appreciate your efforts to rectify my bad experience.
