iLevel Lab review for Variant Option Product Options

THIS APP IS A JOKE! Wish I read the bad reviews first. you can not TRACK INVENTORY! Yes you can do more than 100 variants but that is not transferred back to shopify to enter quantities. So you basically can not put any INVENTORY QUANITIES, PRODUCT SKUS, BAR CODES! Have to mention that the customer support may take several days to reply, and this app will completely mess up your product page layout!!!
