I have been buying Gillette Fusion blades on eBay for over 5 years and have gotten authentic blades every time, until now.
These new blades are obviously fake. They grab and hurt my skin when I shave. They don't shave as close. The blue strip at the top is disappearing, in a large central area, after only two shaves. The "rivets" holding the blades are irregularly placed.
When I get back to my computer I plan to contact the seller and eBay.
