Do Not Buy Cheap Ringa
We thought our rings were getting old and not keeping their seal and got cheap ones from Amazon.
Every batch of eggs for hard boiled (5/5/5) failed to fully cook, I mean like sufficiently cook to Peel the shell cleanly and safely eat.
Paid full price for the rings from the Instant Pot store on Amazon, unfortunately only place I could find them, and voila. Cooked eggs.
Never again.
