Tri-Fold LED Vanity Mirror - 21 Lights, 3X Magnification, Touch Control for Home & Travel Makeup

I don't remember what made me think about buying one of these, but I use it every week. It sits in my home office on my desk and I use it to pluck my eyebrows so I don't have to stand and lean over the sink for an hour and hurt my back. I also use it for face masks. It works by USB but also works by batteries. I use batteries because I don't want to keep it plugged in to my laptop to use. When you turn it on, the lights are very bright. You can tap and hold on the power icon and the lights will dim. If you lift your finger and tap and hold again, the lights will brighten. I really like that you get to control the brightness. I also like that it has a 3x and a 2x part on the right side of the opening doors. This mirror is very useful!
