When I first opened the box I was surprised by the small size of the tools. The description was correct, so that's my fault. The next surprise was the stiffness/roughness of the wire brushes - I was expecting something thinner for this size. Finally, I noticed that the brushes weren't exactly centered, causing the brush to bounce around as it was applied to the surface. The fall wheel was ok. I have to say I'm happy for the price and they did the job I needed them for.
