Product review (5 stars): Compact Surge Protector for Refrigerators
I was searching for a sturdy but small, against the wall surge protector for my 10 cu ft refrigerator/freezer and this product fit the bill. It is compact in size, occupying only half of the wall outlet. It protects against low and high power fluctuations, both of which can impact a refrigerator. Clearly, I have just started to use this product and it has not yet been tested during a storm or blackout, but so far so good. I can give an update if this happens.

In addition, the seller, Kasman Trading, was very responsive and knowledgeable when I had questions about the product.  I had overlooked the built-in time delay and thought the item was not operational.  Kasman Trading did not hesitate to offer me a refund as well as offer to inform the manufacturer. According to Kasman, they receive very few claims (less than 1%) on the volume that they sell from this particular manufacturer.  I would definitely make a purchase from Kasman Trading again.

Here are additional details about the Exceline Electronic Surge Protector: Made for domestic refrigerators up to 27 cu ft, freezers, water coolers and air conditioners up to 5000 BTU.
