I have used, and since lost a Gillette Fusion Power Proglide and I thought finding the same type of razor. So I press the button before shaving and then, surprise, the blades do not vibrate the razor but a lot of noise. In fact, the blade part is made of titanium and 4 only the small part mower blades is activated by the button after removing the protective cover. Shaving is precise and the deck is ideal for small paws, nose hair and eyebrows when on a trip. The shaver is very well finished and the base has two suction cups to secure it on the floor of the bathroom. Fun but not really helpful for me. As is often the blades are not given even if they are cheaper than 5 Gillette blades.
