phonak assistive listening devices

Goodmorning, I use a PHONAK hearing aid and a cochlear implant. About 25 years ago I used the Phonak MICROLINK with great satisfaction. Very useful in very noisy places. I have used it in all places and especially in restaurants, noisy places, hiking trips, ecc… a precious help.
Now I have a Phonak Audeo hearing aid (which is giving me some problems) and I’m using a Roger on. unfortunately this new device is not very useful for me in very noisy places…
I would like to know if there are any users who have had experience with the Microlink, or the Roger Pen and with the last the Roger on. How can I best use Roger on?
Thank you
