Nano SkinGlide coating improves gliding on skin by up to 30%, to minimise irritation. Lift & Cut design guides and lifts the hair in the optimal way, to shave the hair at 0 mm without cutting skin, for longer lasting closeness.
Shaves well, with good battery life, though bigger and heavier than the previous 9000 series shaver. However it has an integrated trimmer AND the head isn't detachable and so doesn't fall off after a couple of years use.
