As others have commented, it's the blades that come with the razor that are amazing. Got mine direct from Gillette here in the UK and I'm still on the first blade. Lost count of the number of shaves but it's well into double figures. Every time I think it will be time to change the blade but no, still smooth, sharp and efficient. Might have to order a few packs though I doubt I'll need them!
