If you have used a dual foil shaver before then this is OK.
If you have always used a wet shave, then you need to try both a rotary head shaver and a foil shaver to see which, if any, suits you.
I don't like rotary shavers and I only wet shave when I haven't shaved for a couple of days and even then I never press hard as I get too many nicks.
As with most things in life a little lubrication, even water, when using a foil shaver goes a long way.
Currently (Aug 2013) the Remington F4800 is cheaper than the F3800, for example Tesco price for the F4800 is £26.
Braun may be the best, but they are the dearest and the price of replacement foils is crazy.
The replacement foils and cutters for this shaver seem to be about £15, similar ones for a Boots shaver is about £12.
Boots brand foil shavers are what I normally use, the shaver new price and replacement foil price is reasonable, but they don't seem to do a rechargeable twin foil at the moment.
The charger only outputs 160ma @ 4.7Vdc, which is why it takes a long time to charge.
You cannot use the shaver whilst it is plugged into the charger, but this is a minor point.
After a month's use I find that the battery life between re-charges is poor.
The batteries are only AAA size Ni-MH and rated at 650mA.
There might be space in the case to fit AA sized batteries, which have a capacity about 1800mA (3 times as much capacity as the AAA size) but I suspect the charging time would be 3 times longer.
