They have their place.

Most of the issues was because of the way that KB has the top ring spaced from the top of the piston....it's a lot closer than normal, which requires a wider top ring gap. A lot of guys would file the rings like they normally would and then they would have issues.

For a budget build, they're absolutely fine. But for an engine that's going to see some abuse, forced induction, extreme rpms, etc., I would upgrade. Forged pistons aren't that much more expensive in comparison.
