I’m actually considering a switch to “Product Extras“. The integration with WP seems better, less buggy and looking better without custom styling. I find it even looks like it was developed as a core WooCommerce feature. Plus, it’s accessible from within product edit screen/tabs.
well, each person has it’s own choice, we got so many responses against this like they like the way PPOM has fields as meta and this can be attached so easily with any product(s).
And about styling, sometimes theme’s CSS or other plugin CSS conflicts with each other. Even we have prefix our CSS.
