Review on Optimized Oral Care with Philips Sonicare DiamondClean Replacement HX6064 by Tony Pearson

On the left is what I got from Revain. On the right is the toothbrush I bought at Costco. A few notable details indicate that this item is a fake. The Sonicare logo is blurred compared to the original. The sign below is smaller than the real one. The biggest difference is that the fake has no electrical interface at the bottom, while the real one lets you see the electrical interface clearly. I think the electrical interface is meant to indicate the exchange. I used the fake for months, never reminded me to replace it. Revane, you should have taken more responsibility to destroy all the fake items!
