Panasonic is on this site seven times: a professional clipper, three foil
shavers, a nose and ear trimmer and two replacement blades.
What we found writing the reviews
Linear motors, and the figure behind them. 39 000 cutting actions a minute
on the Series 700, 70 000 on the Series 800. A linear motor is what stops a
shaver or clipper bogging down in dense hair, and Panasonic states the rate
rather than a marketing name.
The compatibility lists are complete. The Pro X taper blade names fifteen
clipper references it fits, including the ER-DGP84 reviewed here. That is the
only honest way to state compatibility on a clipper blade, and it is why this
site can link the two pages together with confidence.
And it cuts both ways. The WER9930Y fading blade is stated for the ER-DGP86
— one digit away from our ER-DGP84, and not the same machine. Panasonic’s
precision is what lets us say so; a vaguer listing would have left the
temptation open.
The durability claim names a method. Panasonic states the Series 800 shaves
as on the first day for five years, tested by comparing artificially aged
shavers with new ones. It remains the maker testing its own product, and it is
more than most durability claims disclose.
The nose trimmer is the only one here with a vacuum. It draws the clippings
in rather than dropping them, on a head that washes under running water without
removing the blade.
Where the listings go quiet. No runtime on the Series 700, none on the
professional clipper, and the German listing for the ER-DGP84 is written in
Dutch with four bullet points and no figures at all.
