Overview
Supreme Trimmer gives this Vader trimmer a zero gap diamond-like carbon T-blade and a fast motor for sharp edge-ups and line work, with a long-lasting battery, an LED charge readout and a full travel kit.
Crisp lineups and close beard work are what a zero gap T-blade does, and long runtime covers several cuts. The short guard range limits it to detail work.
Who it's for
Home barbers and beard owners who want sharp edges get a full kit with a travel bag. People cutting longer styles need a clipper alongside it.
Pros and cons
- Zero gap for crisp lines
- Long cordless runtime
- LED battery readout
- Travel bag and blade guard
- Short guard range
- Waterproofing not stated
- Blade gap needs careful setting
Performance notes
A zero gap blade cuts very close, which sharpens lines but can nick skin if pressed hard. Motor speed holds steady through dense beards, and the DLC coating reduces friction.
