Title: it's fake!
Review: I have used this kind of brushheads for years and the first 2 days I used my new brushheads that I used ordered worked fine. On the third day it feels very strange when I'm using it, as if it's not really brushing my teeth. I came to check if other buyers have this problem, and I saw some have the suspicion that they are fake brushheads. One reviewer suggests to check this picture with my brushheads, and yes, they look different! The "Oral B" is grey on the ones I just purchased, and the blue part of the brushhead is darker!! I have never got a counterfeit item from Amazon before! I really didn't think that I need to be worried about whether the product is fake or not on Amazon!
