There's nothing worse than a slightly uneven goatee. If you're going to go to all that trouble you have to get it right, and if that involves a shaver/ ruler combo , well, why not? It was been designed by James McAdam as a helpful tool for the 'common man' and could be good way to encourage men to keep their facial hair in shape. i think I'd find it pretty funny if I saw a guy using this, so everyone wins!
