They work for a very short time and the wire bristles break off.
I use the wire wheels a lot. My issue is the they last less than 5 minutes each, the wire pieces just break and fly all over, I find them in my hair and my clothes. It’s good you get quite a few in the 60 as they don’t last long.
Pros
The set is perfect for small and large cleaning tasks
Cons
The set is not suitable for use on walls or other painted surfaces
