I was able to use my new brush for the first time this past weekend. It is extremely more efficient than my last brush and cleaned my boat with ease. I was hesitant about the stiffer bristles but they turned out to be very useful in getting off tough stains from a long day of fishing. I really like the functionality of the rubber gasket surrounding the brush as it was more gently on the gunwales as I cleaned. I HIGHLY recommend this brush!
