The ER-SB40 runs a linear motor at 9,800 cuts per minute behind a dial that steps through 19 lengths from 0.5mm to 10mm. GQ found it clears thick growth quickly with few pulls and rates it a strong tool for short beards and stubble, but a large one, awkward to steer around a jawline and heavy in a wash bag. It is waterproof and runs 60 minutes off a charge.

Strengths
  • — High-performance linear motor delivers 9,800 cuts per minute for efficient trimming of thick, dense hair, per GQ.com
  • — 19 precision length settings (0.5MM to 10MM) with quick-adjust dial for customizable styling, per Average Guy Tested
  • — Waterproof design allows for cordless trimming in the shower and easy cleaning
Watch-outs
  • — 60 minutes of runtime per charge is modest for the price
  • — Large and heavy, awkward around the jawline and noticeable in a travel bag, per GQ.com
  • — The battery gauge shows only full, mid or low, with no minutes-remaining readout, per GQ.com

Philips Norelco OneBlade 360 Face + Body
Ranked #4 in Best Beard Trimmers
Philips Norelco OneBlade 360 Face + Body
2 sources$39.96as of Oct 11

The Philips Norelco OneBlade 360 is a slim hybrid trimmer and shaver with a double-sided blade that flexes on its mount, sold with a 5-in-1 adjustable stubble comb, a skin guard and a body comb. TechRadar used it every other day for two months and found it extremely gentle and precise, with no razor burn, but inconsistent as a beard trimmer on the comb's longer settings. T3 found it gave a surprisingly close shave for the price and that the new comb coped better with longer hair, but its blades dulled noticeably after a few weeks of heavy use. Both note that replacement blades cost nearly as much as the trimmer.

Strengths
  • — Extremely gentle: TechRadar reports no razor burn and recommends it for particularly sensitive skin
  • — Flexing double-sided blade makes shaping around the beard and neck easier than on earlier OneBlades, per T3
  • — Fully waterproof for wet or dry use and easy to clean, according to TechRadar
Watch-outs
  • — Inconsistent trimming: TechRadar got patchy results on the comb's longer presets and says it works better at 1mm or 2mm
  • — Blades dulled significantly after a few weeks of heavy use in T3's test
  • — Replacement heads can cost nearly as much as the trimmer itself (TechRadar and T3)

How they stack up

Panasonic Cordless Precision Beard Trimmer

It is waterproof, as is the Philips Norelco OneBlade 360 Face + Body. Its 60 minutes of runtime compares with the WAHL's 3.5 hours, and it costs more than the other three trimmers.

Philips Norelco OneBlade 360 Face + Body

The Philips Norelco OneBlade 360 trims and shaves with the same blade, where the Panasonic Cordless Precision Beard Trimmer is a dedicated trimmer with 19 length settings against the OneBlade's 5-in-1 comb.
