GN Resound Live 9 or 7 Remote Mic

I am thinking about the GN Resound Live 9 or 7 Remote Mic as an option for me. If you are using these currently, what has been your experience? What have you found to be the advantages and disadvantages? What model do you have, CIC or ITC? Any regrets?

For the experts out there, what are your opinions on the remote mic aids?

Thanks all for your responses. I have a lot to think about right now and information helps with decisions.
