Decent disposables when I go to the gym. Almost impossible to cut yourself, and the blades last long enough to use a few times before they go dull. By design they do not shave as closely as 'regular' razors, thus reducing irritation from dull blades rubbing along your skin. It is possible to get the 'baby smooth' shave with these razors, however you need to 'buff' your skin against the grain with these guys. I had no irritation even when going over the same area half a dozen times (which is unusual, three passes with the mach3 gives me razor burn). The single blade really does help those of us with sensitive skin who have difficulty using multi-bladed cartridge razors on a daily basis. They are also reasonably easy to clean under the tap and come with a useful blade cover to prevent them from cutting your gym clothes while in storage.
One point knocked off because they are wasteful, as Bic does not sell these as a 'shaving system'.
