The long version

Almost every shaver that starts pulling is a worn foil on a working motor. This one is built so you can fix the first without replacing the second.

The difficult part of a rotary shave is not the cutting — it is contact. A head that cannot pivot will either skip over the hollow under your cheekbone or press too hard on your chin. Each of the three heads here sits on an independent two-axis gimbal with 8° of travel per axis, and the head assembly itself flexes at the neck. In practice that means one pass where a fixed head needs three.

  • 12 directions

    Heads that follow the face

    Three heads, two gimbal axes each, 8° of travel per axis, plus a flexing neck. The assembly finds the hollow under your jaw without you changing your grip.

  • 0.06 mm foil

    Close without the drag

    Electro-etched stainless foils at 0.06 mm — thin enough that the cutter rides near the skin surface, stiff enough to survive a dropped shaver.

  • 60 minutes

    Three weeks of shaves per charge

    A 1400 mAh cell gives about 60 minutes of running time, which is roughly 20 shaves. Five minutes on the cable is enough for one full shave when you have forgotten.

  • IPX7

    Shave in the shower, rinse it after

    Sealed to IPX7, so the whole tool goes under a running tap. Use it dry, or with foam and water — the motor holds speed against the extra load either way.

The heads

Three heads that move in twelve directions, because a jaw is not flat

The hard parts of a face are the hollow under the jaw and the ridge of the chin, both of which a rigid head crosses at the wrong angle. You compensate by pressing, and pressing on a rotary head is what causes irritation.

Each head floats on its own gimbal and the plate carrying all three pivots as well. The cutting surfaces stay flat against skin through the transitions, so the pass that used to need pressure now needs contact.

Irritation is a pressure problem long before it is a blade problem.

The motor

It listens to the load and adjusts before you notice

Coarse growth and three-day stubble load a shaver very differently, and a fixed-speed motor splits the difference badly in both directions. The controller here samples load hundreds of times a second and raises torque where the beard is dense.

What you hear is the pitch staying constant across the jaw. What you feel is not having to go back over the same patch.

A motor that holds pitch under load is doing the work you would otherwise do twice.

Wet or dry

Sealed properly, so the whole thing goes under the tap

Wet shaving with foam and dry shaving on the way out the door are different routines, and a shaver that only does one of them well is half a tool. Sealing to IPX7 makes both available and, more usefully, makes cleaning a ten-second job rather than a project with a brush.

Rinse the head open under warm water after every use and leave it open to dry. That habit alone is most of the difference between a head that lasts twelve months and one that lasts six.

Ten seconds under a tap, every day, doubles the life of the head.

In three years

The part number is published before you buy it

A shaver at this price only makes sense as a purchase if the consumable is still available when it wears out. Foils and cutters wear into each other as a matched pair, so they are sold and replaced as a set, never mixed.

Every cutting surface we ship has a part number printed in the manual and listed on the refills page, with a ten-year stocking commitment from launch.

Ask for the replacement part number before you buy the tool.

  • Splash-resistant only — you clean it with a brush

    IPX7 sealed, rinse the whole tool under a tap

  • Battery level is a single LED that means nothing

    Five-segment charge readout plus minutes remaining

The routine

Four steps, in this order

  1. 01

    Start dry and clean

    Rotary shavers work best on dry, oil-free skin. If you are shaving wet, apply a thin foam rather than a thick lather.

  2. 02

    Move in slow circles

    Do not drag it in straight lines like a foil shaver. Small overlapping circles, light pressure — pressing harder cuts less, not more.

  3. 03

    Go against the grain last

    First pass with the grain to take the bulk down, second pass across it. Only go against the grain on the areas that need it.

  4. 04

    Rinse it before you put it down

    Ten seconds under a warm tap, shake it out, leave the head open to dry. This one habit is most of the head life.

Questions we actually get

Before you decide

How often do the heads need replacing?

Once a year with daily use. The shaver tracks running hours and puts a head icon on the display when you are due. Shaving with worn foils is the usual cause of irritation people blame on the shaver itself.

Can I use it in the shower?

Yes. It is sealed to IPX7 and the whole tool can go under running water. Do not charge it while it is wet — dry the port area first.

Rotary or foil — which should I pick?

Rotary generally suits coarse or curly beard hair and faces with more contour. Foil suits fine, straight hair and people who shave every single day. If you are prone to ingrown hairs, rotary with light pressure is usually the kinder option.

Does the travel lock actually work?

Hold the power button for three seconds and a padlock appears on the display. It stays locked through a flight, a bag and an airport scanner.

Will it handle a three-week beard?

Take the bulk off with the pop-up trimmer first. Rotary heads are designed for stubble length; feeding them a full beard will bog the motor and pull.

What is the battery replacement policy?

The cell is serviceable rather than glued in. Out-of-warranty battery service is flat-rate and listed on the support page — we do not want a dead cell to be the end of the tool.

  • Neck finally stopped complaining

    Coarse hair, sensitive under the jaw, and every shaver I have tried leaves me raw there. Two weeks in, no razor burn. The heads reach into the hollow without me pressing.

    Marcus L. Verified buyer August 2026
  • The five-minute charge is not marketing

    Forgot to charge it before a 6am flight, plugged it in while I showered, got a full shave out of it. That is the whole review.

    Sam O. Verified buyer July 2026
  • Great shave, learning curve

    Came off a foil shaver and spent a week dragging it in lines and getting nowhere. Small circles, light pressure, and it clicked. Wish the card said that louder.

    Ben H. Verified buyer July 2026
  • Published part numbers sold me

    I have thrown away two shavers because nobody stocked the heads anymore. Seeing a ten-year stocking commitment in writing is why I bought this one.
