Start by identifying where you’ll groom most: facial hair, body hair, or both. If you want a versatile tool for shaving and trimming, a 3‑in‑1 model like the Nova NHC-666 offers multiple functions in one device. For body or intimate grooming, consider models described for pubic hair care, such as those marketed for both men and women, which provide flexibility in sensitive areas. For travel or daily quick touch-ups, prioritize cordless operation with a portable feel—some Nova tools weigh around 0.4 kg and offer up to 45 minutes of cordless shaving after a full charge.
