Example Input: I cannot believe the way they market these "brush". The handle is not removable! Even my 12 year old son said it was a little odd. This product needs to go back to the drawing board guys. The bristles on the brush are VERY SOFT. As we had trouble holding up the small bottle of water for about 30 seconds, there you go! We both got quite sunburn. DO NOT WASTE YOUR MONEY. I'm sure you're better than this.
Example Output:
Bad review
