Product review (5 stars): Great Product - But Keep Product Packaging with Description Close By Surge Protector ......
I just purchased a new fridge and living in a part of the country that sees a lot of power surges and electrical fluctuations.  I wasn't going to take a chance with frying the electronics in the fridge (which happened a while back and we lost the fridge, the freezer, the whole house fan, the water softener, the garage door opener, and two TVs).  I have since added individual surge protectors to all our appliances (washer and dryer too....) in addition to having an electrician add a house surge protector to the circuit breaker.  After living without a fridge for 5 weeks, I wasn't going to repeat the experience.  This particular surge protector appears to have a buffer for electrical surges and fluctuations.  It cost more than I have spent for surge protectors in the past, but losing an appliance is so much more inconvenient from both a time and money perspective.  I'm not sure how to gauge whether it is working or not.  Time will tell as I just plugged it in a couple of days ago....
12/20/15 UPDATE:  I've had the surge protector on the fridge and it has been working fine.  Today I wanted to test my new generator to understand what power we can count on in a power outage.  The startup of the generator blew out the surge protector for the fridge.  The surge protector turned yellow, which is the 3 minute spike suppressor.  Since I didn't keep the packaging WITH the device, I didn't remember what the yellow light was for and thought the surge protector failed.  The good news is that it did what it was supposed to do and recycled back to green.  I am now adding labels over the spanish words with english so everyone can tell the status of the protector.  Great product except it should have had BOTH English and spanish.  Am buying another for my garage freezer !.
