user: I'm doing a comparative analysis of different products on Amazon, and customer ratings are crucial for my research. I have a list of products identified by their unique ASIN codes and need ratings for ASINs 'B08PPDJWC8', 'B07ZPKBL9V', 'B075H2B962', and 'B08BHXG144'. Could you provide the ratings for each of these products?
