Review (5/5): Improvement over the old
The 6 Blade replacement head was an improvement over the 5 blade. Of course, it covers more area, but the 6 blades allow for a better contour of your head. This means the blade feels more comfortable and because it hugs the head closer it's a better shave. I started using it to cut my chest hair and it works great on that area too! I would recommend trying it out to anyone who shaves with like products.
