Product review (5 stars): Perfection for protection
We had a newer refrigerator go out because of a power surge.  Specifically, during a sever thunderstorm, the power went out then kept trying to come back on but failed 5 or 6 times in a row.  This fried our compressor and computer.  Electrician recommended this device because the action of the power going off and trying to come on over and over again is what did it in.  The newer refrigerators need the 3 minute delay feature this product features and I can confirm that it works like a champ.  I've had it on our new fridge for over a year and there have been countless storms move past central Oklahoma where we live.  Get this and worry no more.
