Hey, my search engine is not working so I don't know if this has been posted before or not, but I'm constantly cutting myself with razors, and the time and mess it makes for me that lives with 4 other people can be annoying, so I thought about electric shavers, but are they able to do the job on your head since i have really thick hair. I've also seen that Head Blade for $15, how's that work? Reviews are appreciated thank you.
