If You Want The Best, Buy The T980
I've had facial hair in one form or another for my entire adult life and have used a wide variety of trimmers over the years.  This one is, without a doubt, the BEST trimmer I've ever used.  It works as advertised, does everything it claims to do, is both easy to use & easy to clean, holds a charge for quite a while, and I have had absolutely no complaints about it.  I've found that keeping a slow & steady pace, as opposed to trying to race around your face, allows the vacuum to do it's job better.  WELL worth the money I spent for it.
