After using this a couple times it stil trims pretty well. The nose hair trimmer works as expected and trimmed the hairs well. I have not used the eyebrow trimmer yet. The normal hair trimming piece works well to straiten up hair lines. The other trimmer I have also yet to use.
This takes one AA battery which is nice because they are one of the cheaper batteries to use. There is a slider that you slide up to turn on and down to turn off. I like the redmetallic matt finish but because of that finish it isn't as grippy.
Overall this is a nice hair trimming set.
