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

These are not as good as Dremel brand, but they last for a decent amount of time if used for what they are intended for. I restore old small equipment engines and these work fine for polishing and cleaning small parts. Other reviews say they do not last, but they are obviously using them for things that they are not intended. These are not made for removing heavy rust or paint. Definitely worth the price for what you get.
