Signia silk bicross your feedback and review please

My wife has 100% loss in left ear and 60-80% loss in right ear.
She currently uses Phonak ITC bicross. She needs a back up hearing aid. Phonak Paradise cross is only available as BTE model. And she prefers ITC model so it is ruled out.

We would like to try Signia silk bi cross ITC model. I would appreciate if anyone using the same, could provide their feedback.
