Verdict

Supreme Trimmer Vader has the longest battery in its class at 210 minutes. DLC T-blade maintains zero-gap precision. USB-C charging. 7000 RPM motor handles dense hairlines without slowing.

The Slimline Pro Li fills the detail gap that full-size trimmers miss. Ultra-slim profile gets into tight areas around ears, temples, and necklines. Carbon steel T-blade cuts extremely close. 2-hour cordless runtime.
