Charger vs. Dry Box?

My cochlear on the ear N7 processors came with a Dry Lux drier. They are ip68 rated and the manufacturer included a dryer.

The Cochlear Kanso 2 processors are also ip68 rated. They came with a combo dryer/charger. K2 processors are dried and charged at the same time.

I am a big advocate of using a dryer on our expensive hearing aids. It’s too easy to take care of them.
