Best way to get product object from wordpress plugin?

I'm using amember 4 and I'm building a wordpress plugin that will provide content/services based on the configuration of the amember product.

I can see how to get a fair amount of information about the user through the Am_Lite object. But, how do I get full details about individual products? I have custom fields in the amember products I need to access from my wordpress plugin.

Thanks

Bumping this...

I'd like to be able to get custom product data without having to load the whole amember system if possible?

I've added a custom field to the product edit form (see code below). I'd just like to be able to access the information entered into those fields from my application, preferably through a product object if possible?

Code:

Am_Di::getInstance()->productTable->customFields()->add(
    new Am_CustomFieldText(
        'print_days',
        'Print days',
        'Comma separated list of days of the month on which reports should be printed. ex. 1,15'
    )
);
