Query: Best I have Used!

Pros: The best trimmer I have ever used. Highly recommended! Also, being able to use it while plugged in is a key feature.Cons: Does "shave" very closely.I use this trimmer to, well, trim my beard. It is great at that! However, when I want to make sharp lines and shave off the rest of the hair, this thing just isn't that "sharp". To get a close shave and fine lines, I have to whip out my Mach 3 and finish off the job.
