Review on Rocaris 45PC Rotary Tool Steel Wheel Brushes Set - Enhanced Accessories for Optimal Performance by Eric Froedge

You get what you pay for. They break down much quicker than better ones, but they're cheaper and you get a lot more bang for your buck. Make sure you wear goggles as you'll be constantly shot in the face with wire missiles. If you have an adjustable Dremel, set it to a lower speed and they work pretty well. If you have a high-speed, single-speed tool, it will self-destruct very quickly. They do their job, the hardest part is getting all the wire out of your clothes when you're done.
