Don't buy it just because you saw the stars; I rated it 5/5 because, 1, I saw up close that the materials are of good quality, and 2, because the company has the specifications on the product's website that you need to know if you're thinking of buying it.

It was installed a week ago, everything is fine so far, no issues, the reason it was installed was purely cautious, because when you have a "cartload" of devices worth thousands of euros in your home and you want to be more sure that surges are much less likely to cause damage to them, well, you don't think twice at this price range.

I chose this one because it has protection for the neutral as well, because as we said, you never know; otherwise, if you think you know, you have to accept the possible consequences.
