What do you think of the Comford Shoulder Cradle?

The Comford Shoulder Cradle comes in three models (in addition to regular height and tall height). They come in plastic, which is the lightest weight model. There is also a silver model and a gold model. Both the silver and gold models are heavy, which is meant to act as a counter weight to make the scroll of the violin feel lighter. Both the silver and gold models have a "resonating" chamber built in to them, which is supposed to enhance the tone of the violin.
