Review on 300-Pack Steel Wire Brush Set With Rotary Tool Accessories - Rocaris Wire Wheels, Pen Brushes Kit For Improved Cleaning And Polishing by Patrick Biletnikoff

Satisfied. I like the substantial quantity and variety in the package. They clean and remove rust in crevices and corners well enough for my purposes. The cone shaped brushes will shred under anything other than light use. My roto tool's slowest speed is 10,000 so perhaps at a lower speed they would last longer. I'd like to find something similar with heavier wire but I'm sure that most are made very similar.
