Linen and Letters review for King Product Options, Variants

I upgraded to Shopify 2.0 and needed the assistance of this app to organise a lot of my product variants. I contacted their support on many occasions over the last 48 hrs and they were always fast to reply finding solutions to all my problems . The app works seamlessly with my Shopify variants and saves me hours of work. I highly recommend this app. Thank you for all your help !
