I cannot agree more with what Waine said. The HeadBlade is definitely the best device to shave your noggin. In South Africa, the cartridges for a Fusion work out to about ZAR 60 each (about $6.50), whereas a Gillette Contour Plus (Atra Plus) costs around a tenth of the price and fits the HeadBlade. Both the Fusion and the HB do a great job of head shaving, but at the rate you go through cartridges shaving your head, it seems ludicrous to opt for the more expensive option.
