After 12 years my beaten Gillette Power Nitro gave up the ghost, the battery compartment broke off while shaving. Now, after 12 years may also happen (every 3 days in operation). I immediately went in search of a new, and had quickly found one. The ProGlide Flexball is very good at handling, the vibration is very suitable for sensitive skin, it is fully seated behind Power! Many were upset about the price. I must say, the price of the razor in my opinion is fully appropriate. What bothers me is just the price of the replacement blades. This was before but not better. The only thing I am sorry, that is nowhere described on the packaging how to change the blade. Since I'm curious when the time comes, how to do that. You maybe do not like to believe, but the Flexball makes shaving truly simpler and easier. Highly recommend him and would currently buy it again at any time.
