Review on Coarse Crimped Carbon Coated Shank 20 by Drew Diaz

As another reviewer said, the density of the wire bristles in these devices is lower than that of the individual wire brush heads, but what makes them good value for money is that the huge amount of wire brushes you get. They're strong and dense enough that they're great for the weekend warrior or crafter, as a set of this size will last a considerable amount of time even if you work through it faster. If you're a pro who needs to use them daily, you should definitely ditch them and look for a more reliable spoked wheel.
