It is a surge protector. Ideally, I will never experience a surge and need to discover if this really works. I feel confident with the surge protection and grounded lights both on that I will be protected if anything does happen. I like the two outlets on the side. You can plug in a bulky cord without it covering the plug ins for another outlet. I like that the plug that goes into the wall is flush with the wall and that the furniture that I have in front of the outlet does not need to stick out.
I would recommend this to a friend!
