oneisall Metal guide comb review

The same class of clipper as the Pro Upgrade with metal guide combs instead of plastic ones, four hours of runtime, and stainless blades. The combs are the reason it costs more.

What we take from it Buy it for the combs. Everything else is the same hobby clipper as the cheaper oneisall, and the combs are what stops a thick coat coming out stepped.

What it is

A cordless clipper at 6,800 rpm with a 2,000 mAh cell rated for four hours, stainless blades, and four metal guide combs at 3, 10, 16 and 25 mm (0.98 in). oneisall quotes 55 dB.

The comb is the tool

On a clipper, the blade sets the shortest possible length and the comb sets what you actually leave. A comb that flexes under load leaves a step; a comb that stays put leaves a line you can blend. That is the whole difference between this machine and the cheaper one above, and on a thick coat it is visible from across the room.

Runtime and charge

Four hours, with an LED indicator showing the state of charge rather than a single light that changes color at some unspecified point. On a machine you use twice a year, knowing whether it is charged before you start matters more than the runtime itself.

Noise

55 dB against 49 dB for the Pro Upgrade — oneisall’s own figures, measured their own way. Both are quiet by the standards of this page; the cheaper one is quieter.

What we rate, and what we flag up

Strengths

  • Metal combs do not flex under a dense coat — the single most common cause of a stepped finish
  • Four hours of runtime with a charge indicator that shows the state rather than a color
  • Combs to 25 mm (0.98 in), so it trims as well as clips
  • Listed on all six of our markets

Compromises

  • 55 dB, six louder than the Pro Upgrade above
  • Four combs, where the vacuum kits ship six
  • Metal combs are colder against skin than plastic — some animals notice on the first pass

The questions owners ask

Do metal combs really make a difference?

On a dense coat, yes. A plastic comb flexes as the hair loads it, and the flex is what lets it lift or pop off mid-pass, leaving a step no blending hides. Metal holds its spacing. On a thin single coat you will not see the difference at all.

How does it compare with the Pro Upgrade?

Same family, same 2,000 mAh cell, half an hour more runtime, six decibels louder, and metal combs instead of plastic. If your animal is noise-sensitive, take the quieter one. If your problem is the finish on a thick coat, take this one.

What length should I leave?

Longer than you think on a first attempt. 25 mm (0.98 in) tidies, 16 mm (0.63 in) is a visible trim, 10 mm (0.39 in) is a clip, and 3 mm (0.12 in) is very short — short enough that a pale-skinned dog should not be left in the sun afterwards. You can always take more off; the coat takes months to come back.
