I have been curious to try one of these brushes for a while, and this one did not disappoint. It feels very solidly built, but what I like most is that the bristles are exactly the right stiffness. Soft enough for it's intended use to clean the carpets in your car, but stiff enough that it would be handy for other uses as well. The bristles are clear, so should be easy to spot if they are getting crusty. The difference between just a vacuum or even wet vac of your carpets and hitting them with some cleaner and a brush is dramatic. It also got into the cracks and crevices of the pedals, and would be great for carpeted floor mats. It's a great addition to your car cleaning gear even if you don't get really into detailing, and a dirty carpet REALLY takes away from the overall look of your interior. Worked great on the slower speed of my driver. The next test will be to see how it works on grout! Should make cleaning a lot of things easier!
