There is a recall on some 1st gen Beal Birdie belay devices. Information on how to check if your device is affected and what to do next is here:

Mods: Would it be a good idea for any product recalls to be 'pinned' posts...?
I submitted my details on the 18th Feb; the original reply said they would send a shipping label for me to return the device. Parcel arrived today with no shipping label but one new Birdie. All's well that ends well.
