This is a very nice and handy device to have to the bathroom, you can trip you eye brows, nose hair, beard, and side burns. I love this little device, it helps me out when I need it and it works like a charm with no problems at all. All it takes is one AA battery and your good to go. I like the beard trimmer because I don't have to worry about cutting myself with the shaver. Overall, it is really nice and really easy to use. This works for traveling as well so you don't have to bring the full sized device, all you need is this one and your good to go.
