Overview
Rotating dual edge stainless steel blades inside a curved head clip nose and ear hair from the top and sides without pulling. The pen grip body runs on a single disposable battery, and water drawn through the spinning blades flushes out clippings.
Wet and dry use plus tap cleaning make this a low fuss trimmer for the sink or the shower. Brows and beard edges can be detailed too, though it is not meant for very short stubble. There is no charger, so a spare battery replaces recharging.
Who it's for
Suited to quick grooming over the sink or in the shower, and to travel bags where a charger is one more thing to carry. Shavers who need adjustable length combs or a close stubble cut should choose a different trimmer.
Pros and cons
- Rinses clean by switching on under water
- Safe for wet use in the shower
- Dual edge blades cut from top and sides
- Angled blade avoids pulling nose hair
- Battery not included
- No length guide combs listed
- Cannot trim very short hair
- Color conflicts: blue in specs, black in title
Performance notes
Cutting comes from rotating blades behind a curved guard, so hairs are clipped as they enter the head rather than pulled. Runtime and speed depend on the alkaline cell, and power fades as it drains. The vortex rinse works only while the motor runs with water flowing through, with the brush for stubborn residue.
