to nassrasier-way with foam: Great idea, works really well and is extremely gentle ... but unfortunately the foam under the foil can not be removed almost. the stuff hiding in crevices all. Cleaning takes then disproportionately long. That should solve Panasonic better.
the battery lasts a week with me approx. a longer battery life would be desirable; but at the price fully OK.
Despite the foregoing points: 5 stars !! as with other manufacturers already cost the shaving parts more (Philips) as the complete shaver from Panasonic. even if the razor survived "only" 3 years he will last as long as my last premium shaver Philips brand for 190 euros. so an expensive trash I never buy again. because you get to the hotline just a shrug and a "That's life" claim, because, unfortunately, unfortunately, is the guarantee to yes ..... I can do without it.
Addendum: the battery is by now more than a year as well as defective. on can only shave 3 times and then one has to reload. Therefore, I have made a devaluation 3 stars is the maximum. let's see what Panasonic makes and what does the warranty request .....
