Query: Single Plug Surge Protector

I purchased two of these units for my two refrigerators. There's room to fit any other appliances near them, so only one plug is necessary. Both units arrived functional and have been performing to specifications. I'm crossing my fingers that they won't have to protect my refrigerators from a power surge, but if such an incident occurs, and I actually notice it, I will be sure to update this review and report on their performance.
