Review on Walter 13G303 Twisted Threaded Diameter by James Womble

These brushes do a good job and hold up very well even under very heavy use. Don't be put off by the price. The old adage "you get what you pay for" applies to this product. We use them daily in the auto shop and this brand and this product in particular is holding up better than anything else we've tried. Please note that they are used for HEAVY cleaning and are very aggressive and will get the job done.
