Overview
Wahl packs four swappable heads onto one rechargeable lithium ion body in its Stainless Steel Slate grooming kit. A wide T-blade trims beards and hair, a detailer handles lines, a rotary head does nose and ear, and a dual foil head shaves.
Range is the strength: one charger and one body cover beard shaping, touchups, nose and ear hair and close shaving, with combs for many lengths. Missing details matter, since nothing confirms whether it can be rinsed or used in the shower.
Who it's for
Frequent trips and small bathrooms suit a single cordless body with many heads. People who shave in the shower or want a dedicated full haircut clipper should look at other models.
Pros and cons
- Four attachment heads in one kit
- Long run time per charge
- Ten guide combs for many lengths
- Works on worldwide voltage
- Water resistance not listed
- Small trimmer body, not a full clipper
- Needs a full charge every half year
Performance notes
Run time comes from the lithium ion cell, which loses little charge while stored, so the trimmer is ready after weeks in a drawer. Cut length is set by the comb on the T-blade, while the foil head gives the closest finish on cheeks and neck.
