45 degree back extension machine vs. ghd back extension machine

I've searched the forums a bit for this but haven't been able to find any definitive answer.

I've seen that the 45 degree back extension machine is bad for you, but no reasons why...

why is it bad? It's the only thing my gym has. Am I losing anything by using this machine instead of the typical GHD machine?
