Observations from a previous Norelco owner:
This unit does an entirely adequate job of beard trimming.  The settings match up well with those from earlier units and, once set, there is no slippage from one setting to another.  In my estimation, the "turbo" feature adds no functionality, only noise and increased battery drain.  The new vacuum feature allows for the capture of only about 60-70% of the hair trimmed.  A potential positive is not having to oil the blades, but only if this does not shorten product life.  And as with the last trimmer I owned, the NiCad battery is not replaceable, but it should be.  The battery is the size of a standard AA but it is soldered in place.  Directions are given as to how to remove the battery prior to disposal, but Norelco could have gone the final step and made the battery replaceable.  My old trimmer worked fine; only the battery needed replacing.  But then again, I would guess that product longevity does not rise high on the list of marketing features.
