Wet and dry compatibility means it can be rinsed under running water or used with foam in the shower. No additional accessories or software are included in the package.

Questions about this item

How often will the 10-position guide comb need replacing?

The comb is a durable plastic attachment with no moving parts; it only needs replacement if the adjustment slider cracks or the teeth break from impact.

What stops the comb from staying locked at 21 mm during a long session?

The slide-lock mechanism relies on friction detents; heavy pressure or clipper vibration can push it back toward a shorter setting.

Does the comb trap heat against the T-blade during all-day use?

The open-tooth design lets airflow reach the blade, so heat build-up matches running the trimmer without any attachment.
