Chime back in after 6 months, let us know (or PM me) how it goes. I bought 1 Durablade here, don't think it's a fake, but old version and not cheap.
Had an Amazon sale in US, so bought 3 more cheaper 3 total less than the 1 here, and since nephew had parcel coming over anyway, just added to his shipment. He kept one, so had 3. One bought locally just died, maybe 2 yrs old. Other 2 are just OK. Bought 10 heads last year, again, great sale, and sent over again. Heads last about 1 year, so much for the 5 yr warranty, though expected, and only cost $6/฿200 each.
I was barely getting 1 shave from the 2 blade Gillette razors sold here (made in Mexico), maybe.
No electric will shave as close as a blade against your skin, that's just impossible. But I'm also not going to the office everyday. Shaves that added 10 yrs of grey off. Always had a lite beard until more salt than pepper ... way to vain for that BS.
