Drying station for hearing aids: WIDEX DRY GO

This new electronic drying station is the perfect way to care for hearing aids and earmoulds. Small, portable and easy to use, the WIDEX DRY-GO UV™ cleans and dries hearing aids overnight.
The DRY-GO UV uses a convective air flow to dry the hearing aids and earmoulds and extends the lifetime of the hearing aid.

How often do I need to put my hearing aids in Widex Go UV?   like Every night is ok?

The drying station makes a tiny sound, even when not operating. Is this an error?

Where can you buy this? There is no link to a site that sells them, at least I didn't see it. Seems strange to post a video and then not say where you can buy them
