The stars aren't bc of their service bc I do not know. I was curious so I came to look at reviews. I have never seen reviews that didn't have one negative thing to say. Either they are God or a fraud. Hopefully, they are as good as the 500+ reviews I've read. It just seems to good to be true. I want to believe but only one 3star and the rest 5 stars. I don't know but I won't judge until I know for sure.
