Summary: Bought as a present but ladies please dont buy this for your fellas! I could live with the average shaving performance if the foils, which tend to need replacing frequently, we're not so expensive. The real con is that you have to buy new cutters which you don't need. Looking on eBay it is almost as cheap to buy a new one - not that I shall be buying another! Big tip - check the price of the spares before buying any shaver and don't buy the F5790.
Summary: I've had this razor for about a year, so a good time to review. Anything more than 24 hr stubble it struggles with. It will not even touch grey hair, so i have to go over my face with a BIC to catch the hairs missed. Unfortunately i'm skint at the moment so instead of a new razor i'm having to make do with buying a new foil for this one, which incidentally comes with trimmers which i'll never use.
Summary: I thought I could save myself a few quid by buying this, but it has been a false economy. I can't get on with it at all. It leaves me sore and picking at stray hairs all day. After two months I have bought a Braun, which I have always used in the past. Twice the price but three times the quality. I won't make the same mistake again.
