I got one of these for my sister for a Christmas present. Usually facial cleansing brushes run pretty expensive, but I found this one for relatively cheap, and I knew she was looking to get one for a gift. After hearing her rant and rave about it, I went out and bought one for myself. I thought that my face couldn't get any smoother or cleaner when I used it for the first time. The brush spins and cleans away any dirt, oil, grease, and makeup. I used it with different facial cleansers and even bar soap, and it helped me remove so much more dirt and dead skin than I am able to remove just by scrubbing with my hands. I am a huge fan of the PROx brush. My skin feels super rejuvenated after using it, and so much smoother than if I was using a facial scrubber or a washcloth. It takes batteries, and I haven't had a problem with it getting wet in the battery port or anything, and I leave it and use it in the shower most of the time. This was one of the best things I have bought to cleanse and smooth my skin.
