Overview
Switching heads on one handle turns this Braun kit into a beard trimmer, hair clipper, body groomer, ear and nose trimmer and small foil shaver. A Precision Wheel sets the cutting length in fine steps, and attachable beard and hair combs carry the range up to longer cuts.
Range is the reason to own it: one handle covers stubble, fades, body hair, ear and nose hair and spot shaving, with length dialed on a wheel that works with the beard and hair combs. The charging time is not stated, and the accessory count asks for the included case to stay organized.
Who it's for
Home groomers who shape a beard, fade their own hair and tidy body hair will use most of the heads in the box. A person who wants just a single beard trimmer or a daily full-face shaver should look at a simpler tool.
Pros and cons
- Covers beard, head, body, ear and nose
- Fine length steps on one wheel
- Long cordless runtime per charge
- Charging stand and organizer case included
- Charging time not listed
- Many separate heads to store and swap
- Plastic housing rather than metal
- Hair comb tops out at a short length
Performance notes
Cut length is set by the Precision Wheel moving the comb in small increments, so consistency depends on holding the comb flat against the skin. The ProBlade head and AutoSense system govern how evenly it moves through thick or uneven hair, and the lithium ion battery supports long sessions away from an outlet.
