Seven products, linear motors, and compatibility lists written out in full
Panasonic is on this site seven times: a professional clipper, three foil shavers, a nose and ear trimmer and two replacement blades.
Linear motors, and the figure behind them. 39,000 cutting actions a minute on the ES-ALT4B (Series 700), 70,000 on the ES-LV67 (Series 800). Panasonic presents the linear motor as what keeps a shaver from bogging down in dense hair, and states the rate rather than a marketing name.
The compatibility lists are complete. The Pro X taper blade names about 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.
The durability claim names a method. Panasonic states the ES-LV67 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, but the method is stated.
The nose trimmer has a vacuum. The ER-GN300 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 ES-ALT4B and none on the professional ER-DGP84 clipper; the ES-RT37, by contrast, publishes its battery in full.
Linear motor · X-taper 2.0 blade · carbon-titanium coating
A professional-tier clipper built around a linear motor that Panasonic states holds its cutting speed regardless of hair density, and an X-taper 2.0 blade with a diamond-like carbon coating. The most expensive machine in this group by a wide margin.
Best for: Cutting hair often, or cutting thick hair, where a motor that stalls is the reason to replace a machine.
≈ $200
Dual-edged blade · vacuum system · safety cone · washable under running water
The one trimmer in this family with a vacuum system that draws the cut hair in rather than dropping it, on a dual-edged blade, a high-torque motor, and a body washed under running water without removing the blade.
Best for: Trimming over a clean basin, or over no basin at all.
3 blades, 30° nano-edged · linear motor 39,000/min · beard sensor · 8-way head
Three Japanese stainless blades ground at 30 degrees, a linear motor running 39,000 cutting actions a minute, a beard density sensor, a head flexing in eight directions, plus a shaving-foam mode, a travel lock and a three-minute quick charge.
Best for: A dense or uneven beard, shaved wet with foam.
5 blades · linear motor 70,000/min · 16D flex head · beard sensor
Five blades, a linear motor at 70,000 cutting actions a minute, and a head that moves in sixteen independent directions. Panasonic states the steel blades shave as on the first day for five years, tested against artificially aged units.
Best for: A thick beard shaved daily, where the number of passes is the actual complaint.
≈ $185
3 blades · pop-up trimmer, 30 blades · 54 min · rinsable
A three-blade foil shaver with arc-shaped foils shaped for under the chin, a pop-up trimmer carrying thirty blades of its own, an hour to charge for fifty-four minutes of use, and a head that rinses under running water.
Best for: A daily dry or wet shave, with the head rinsed at the tap afterwards.
≈ $120
The replacement blade for Panasonic's professional clippers, sharpened at 45 degrees with a diamond-like carbon coating, and listed as compatible with fifteen references including the ER-DGP84.
Best for: Bringing a professional Panasonic clipper back to a new cutting edge.
A fading blade for the Panasonic ER-DGP86. The listing states one compatible machine and nothing else — which, on a clipper blade, is the whole specification.
Best for: An ER-DGP86, and nothing else.
