Review (2/5): Not quite the best thing after sliced bread...
I bought the Philips Norelco T780 Rechargeable Vacuum Trimmer because one of their earlier, humbler trimmer was great...I used that for about 8 years (4 in India) before I simply misplaced it...so needing a new one.
But this new one is rather wimpy in function...especially on a good length beard...and the vacuum is largely cosmetic.
