Review (1/5): Wear your glasses!
It trimmed without inflicting pain. Thats the best I can say about this machine. The setting indicator is so small I need my reading glasses to insure I've got it right. Swiching to the sideburn/edge trimmer involves removing the adjustable guide, the trimmer head, and replacing with the edge trimming head. Part alignment must be perfect of they don't fit. Replacing the guide comb requires precision as well. A pop-up trimmer would have solved those problems.
The vacuum is gimmick that works more or less, but the recepticle can pop open without warning and dump lots of little trimmings everywhere. The carrying case does not seal... just a velcro flap... so when packed, bristles can get spread around your suitcase.
I dropped it yesterday, and broke one of the trim heads. I was unable to find replacement parts online, and I must say I was relieved to be forced to replace this unit with a better designed model.
