Cheaper than Mach3, Quattro & Fusion, gives a good shave. Not as durable, made of flimsy plastic. This is a good alternative to the much more expensive Mach3 from Gillette.

None that I can think of. Very irritating. I don't understand why razor companies keep making more and more razor blades on each razor. It just gets more and more irritating the more blades you put on there. Two blade shaving is way less irritating than this one.
