Having now tried this I find that in some areas it's lacking, but in others excellent.
Starting with the positive -
Sideburns - very impressed, did a really neat job.
Ear hair - best thing I have ever used. Ear hair no more!
Eyebrows - not so impressed. Trimmed some but the wild ones still remain.
Nose hair - not at all impressed. Had to resort to scissors to get the offending hairs.
Being battery powered has pros and cons. Pros - it's extremely portable and easy to take on trips away from home.
Cons - the battery is going to run out, eventually, but it only takes one AA to power, so that's pretty cheap.
So overall, pretty good or not depending on what you want it do. I will certainly continue to use for the areas it works on. Bit disappointed it doesn't do it all and I can't reduce to one bit of grooming kit.Philips Series 5000 NT5171/15 Nose, Ear & Eyebrow Trimmer with Facial Styler
