You have to define exactly what that means.

I agree that they are NOT AS GOOD as O.S. and Saito, in that both of the latter have higher tolerances and better builds.

That said my Magnums have lasted over six years of hard use, so I cannot call them "junk" either.

I prefer the Magnums over the Evolution engines.

Maybe in another six to ten years they'll not be running, but my similiarly aged OS's and Saitos are...

But I've already gotten my moneys worth on the first period of time.
