This is an adorable little shaver. It's cute and easy to toss in your purse to have on hand when you are in a pinch and need to touch up areas.
With that said this is not good for a complete shave of any part of your body. To test it out I used it under my arms as well as in the center of my eyebrows and at my temples where I have a few stray eyebrow hairs. I didn't have a good experience under my arms. The shaver actually irritated my skin there for some reason. I didn't like it that's what I do know. Now for the little strays between my eyebrows and my hairline at my temple this device worked decently and easily shaved the hair away. I used it in between my brows in between waxings to see the results of the razor and it got a few of the fine hairs and left the 3 or 4 more coarse hairs in place. So from my experience, this shaver removes fine hairs with ease but any hair with the slightest bit of thickness to it didn't budge. That's why I said I suggest using this for a quick touch up in a pinch because you aren't going to get more out of it than that which was a bummer for me. I had high hopes.
