Looking for implementing Salesforce industry solution for Wealth Management domain. Came across free AppExchange product 'Salesforce for Wealth Management'. Can someone please provide pointers on the below:

• Whether it fully caters to a typical Wealth Management domain?
• Is is totally free of cost?
• Once installed, will be available as a managed package?
• To what extent can it be customized?
• Is is the same as industry solution?
