This is a very handy tool to have. I travel a lot and sometimes I don't have time to shave in the shower before work. There are other times when I start out wearing pants but want to change to shorts as the day warms up and I notice that i've missed a spot. It's so refresing to have the shaver with me in my car or purse so that I can quickly touch up my legs. I also have tattos on my arms and shave my arms. There are days I'll look down and realize I forgot to shave my arms and it can be embarrasing at work so I love being able to quickly pop in the restroom and take care of it.
I wish that it was rechargable and came with a wall charger instead of having to use batteries, but that is really the only think I dislike. If you have thicker hair you may have to go over a spot a few times to get a smooth shave.
