Widex Scola FM system- good?

Hi, I use Widex Inteo. I hear much better. But in loud environment, it is hard to listen to friend’s voice, so I am thinking to buy Scola FM system.
Please let me know if it is good and how much for both hearing AID.

I desperately need Scola so that I can join friend’s conversation!!!

scola = old Oticon lexis
it works fine
