I love this brush. I’ve had it for almost a year, and it’s pretty good! I got a new face wash, and then after a while I bought this. A charge lasts a long time. I charged it when I first bought it and haven’t since - and I use it 2-3 times a week. The only reason I give 4 instead of 5 stars is because recently I started breaking out every time I used the brush. I know bristle brushes store bacteria quicker, which is why I bought silicone. It’s been almost a year, so I’m surprised it lasted this long. However, I think that is my own fault. I store my brush in the shower. I don’t put it away in a closet or anything. So the moisture probably helped bacteria grow faster. If you buy this, store it somewhere dry!
