Title: Reliable & well-made, but vacuum sheath decreases precision when using without numbered head.
Review: I had a Philips trimmer that lasted me 7 years. It's still running but the battery can no longer be charged. This new trimmer is great so far, except for one feature: the vacuum system has a plastic sheath right infront of the trimmer teeth, and if you want to cut or shape your beard using the naked trimmer without the numbered head, it becomes difficult to gauge where the trimmer is cutting because of the obstruction.
