Query: Not as described

This set is described as 4-5/8" diameter. It is not. The discs are only 4" in diameter. Have not used them, returning them. However, I did notice one balancing hole in the top disc (didn't open the package to see the second one). This means they are not precision machined/ground. If you look at the CMT and other quality stabilizers, they do not need balancing holes because they are precision machined. Yes they are more expensive and for good reason. Also, the other brands are a full 5" diameter.
