Not that you need additional convincing, but about 10 years ago I bought the IGEA radio frequency product. I hadn't thought in advance that I would be trying to affect a single hair. Do you know how difficult that is and what an arduous process it was? I don't think I even had it a week before I threw it away. Lesson learned.
I stick to trimming, tweezing and shaving. In the end, I simply view it as another task to prevent myself from turning into an old troll
