Gillette's bad interface
Gillette is on my shit list.
Well, the title is misleading. The real problem is incompatible interfaces due to their “innovative” upgrades. Gillette have pioneered in razors with 2, 3, 4 and 5 blades. Whatever next!?
Incidentally the price for 5 sensor excel double-blades are 5.5USD in Argentina.
Their newer Mach3 Turbo triple-blade set of 4 (not 5) costs about 8USD. I recall that being a lot cheaper than the UK.
