WooCommerce return product object by id

I am creating a custom theme for woocommerce and I need to be able to create a mini product display. I am having problems finding documentation on the woocommerce api. I have a comma delimited list of product IDs that I need to iterate through and display a custom mini product display for each in sequence.

$key_values = get_post_custom_values('rel_products_ids');
//get comma delimited list from product

$rel_product_ids = explode(",", trim($key_values, ",")); 
// create array of just the product ids

foreach ( $rel_product_ids as $pid ) { 
    //sequentially get each id and do something with it

    $loop = new WP_Query( array( 'post__in' => $pid ) );
    // also tried ...
    //$loop = new WP_Query( array( 'ID' => $pid ) );

    while ( $loop->have_posts() ) : $loop->the_post(); $_product = &new WC_Product( $loop->post->ID );
        //do stuff here I have stripped the html in favor of getting to the meat of the issue
        woocommerce_show_product_sale_flash( $post, $_product );
        if (has_post_thumbnail( $loop->post->ID )) echo get_the_post_thumbnail($loop->post->ID, 'shop_single');
        get_permalink( $loop->post->ID );
        the_title(); 
        $_product->get_price_html();
    endwhile;
}

Any help would be appreciated.

Thank you,

Another easy way is to use the WC_Product_Factory class and then call function get_product(ID)

http://docs.woothemes.com/wc-apidocs/source-class-WC_Product_Factory.html#16-63

sample:

// assuming the list of product IDs is are stored in an array called IDs;
$_pf = new WC_Product_Factory();  
foreach ($IDs as $id) {

    $_product = $_pf->get_product($id);

    // from here $_product will be a fully functional WC Product object, 
    // you can use all functions as listed in their api
}

You can then use all the function calls as listed in their api: http://docs.woothemes.com/wc-apidocs/class-WC_Product.html
