I received this (Good or Bad) news just now.
I can see that even my Penetration Testing Student course purchased in 2014 Lab is active now.
I think it is good if you want to go back to the lab to check something, but bad because you don't have the pressure to finish before LAB time expires.
“Your lab hours have expired” is no more! We’re glad to announce that Hera lab hours now have lifetime validity, and you are free to use them up whenever you want.
