Body grooming your clients can do without nicking themselves.

The Supreme Trimmer TESTii STH120 is a fully waterproof cordless body, groin and bikini trimmer with a skin-safe blade system and USB-C charging. It ships with three comb attachments at 1mm, 3mm and 5mm, so length is set by the guard rather than by how steady the user's hand is. For barbers, it is a retail item that solves the request you get asked about but do not perform in the chair.

Trim sensitive areas without irritation: a skin-safe blade system engineered to glide rather than grab.
Use it in the shower: a fully waterproof body rated for wet or dry use.
Repeatable lengths every time: three comb attachments at 1mm, 3mm and 5mm.
Charge it with a phone cable: USB-C rechargeable, no proprietary adapter.
Discreet on the body: a quiet-run motor and a travel bag included for the gym or a trip.

Questions Barbers Ask

How long does the TESTii run per charge?

Supreme Trimmer's published figures do not agree. Its own website states up to 100 minutes, while its Amazon listing for the same STH120 states 90 minutes. Rather than pick one, we are telling you both figures come from the manufacturer and conflict. Supreme Trimmer does not publish a charge time at all.

Can it be used in the shower?

Yes. It is a fully waterproof design intended for wet or dry use. Supreme Trimmer does not publish an IP rating.

Is it safe for the groin area?

That is what it is built for. The skin-safe blade system is designed to move across sensitive skin without pulling, and the 1mm guard keeps the blade off the skin entirely if the client prefers.

Is this a barbershop tool or a retail item?

A retail item. Barbers stock it as an add-on sale for clients asking about body grooming between visits.

Why Barbers Love It

It answers a question you get asked and cannot help with. Clients want body grooming advice from the person who cuts their hair, and pointing at a shelf beats a shrug. The three guards are the part that keeps it from going wrong at home: the failure mode on body trimming is going bare-blade on skin that has never seen a blade, and a 3mm guard prevents that entirely.
