This facial brush is amazing! This is my first facial brush purchase. I stumbled upon this product at TJMaxx and for $9.99, I had to give it a try. The brush is powered by 2 AA batteries (not included) and is waterproof. Mine came with two brush heads. I was in awe the very first time that I used it. It cleans really well and exfoliates the skin. My face feels super smooth after using it. I would most definitely repurchase!
