Review title is Works! And seller replaced the defective unit 🙂 [SEP] Definitely zapping some of those course hairs.  Mine does not seem to function the way intended. The knob seems to control nothing. Does not turn it off or change charge, seemingly. When I hold in my left hand, my finger gets zapped a bit, but not in my right hand. I am thinking it’s because I have my Apple Watch on my left, so be sure to remove all jewelry first!<br /><br />I watched a video on you tube first.  I have red hair and some of my hair is dark at the tip and light at the root plus I have freckles. This can make finding the follicle/pore challenging. However I have removed a lot of these suckers. Even removed an especially egregious one from my upper lip. No more painful than tweezing. After I finish my chin, will prolly go for the upper lip stash hairs.<br /><br />Clue that you are in the right spot is when a lot of the white stuff comes out right away. Definitely a home run 😃. One star off for the control knob issue.<br /><br />I should have returned it immediately for exchange when I realized it was not working properly. But I reached out to the seller and they will replace the defective unit. So 5 stars
