Great...if you're a MASOCHIST


Light is cool and it looks slick.

Yanks every other hair out of your nose. It is basically unusable unless you like pain. I bought this to replace an old nose hair trimmer that looked really beat up...but still worked. I'm back to the old's ugly but it works.

Ease of use.

Speed a little slow in removing hairs, but still does the job.

My other nose trimmers got to were the battery would not hold a charge, this made the trimmer not cut very well in turn it would pull the hair, ( ouch ) you know how it felt,...But this new one runs great and fast cutting smouth easy to use. I...

Battery would not hold chsrge, resulting in bad operation.

Panasonic Nose & Ear Trimmer with Light ER421KC


I hope this unit will last as long as the first

this trimmer gets the job down without pulling out nose hair I bought my first unit 2 years ago and it works very well. it was time to get anew one and it just so happened Newegg had it on sale through a third party Barska great shipping time

Required Engineer's Tap


Lost cost bet for better hygiene.

Works, but not until I gave it a firm engineer's tap. Blades work well at removing ear/nose hair.

Sounds sickly, I don't expect it to last too long. Really, a light? Do you think I'll be grooming in the dark? It'll be a nice salvage led once the unit is declared dead.

Wow! No pain.


Trims inside nose without pulling or grabbing. Also trims eyebrows well. Even managed to extend hair cut time by a week by trimming neck hair.

Had to manipulate battery to get stable power. At first I thought it was DOA (no power), but after reinstalling the battery with a few twists it came on and has worked since.

It cuts the hairs well without painful tugging.

The light is useless.

Really bad quality control


So during the first couple of weeks it was ok- motor spinning decently and it was doing its thing, if somewhat painfully. However, after a couple of months, it completely degraded into a state where it was barely working at all. Extremely slow spinning...

Weighs less than 20 lbs?

Does a more painful job than other devices Breaks after a few weeks- look at everyone else's reviews Becomes essentially worthless

Works very well. Does the intended job. Quiet

Light seems useless. Sounds under-powered but works. When I first got it it would not work. After taking the tip apart and reassembling it it has been working as a charm. ever since
