ONTARIA review for Key Product Options, Variants

The legacy SC Product Options have been the most important and indispensable part of every single product page of my store. The additional profit from this app was roughly 100 times its cost. No, I am not kidding. So when the new Keystone Production Options came out I wanted to migrate on the spot. The migration was straightforward but wanting to change a few other things on the product page I messed up my theme and the checkout did not work. Having had forgotten to back-up my theme I turned to Keystone for help in panic. Ejub responded within minutes and Ahmed fixed the problem overnight. I cannot praise the app, the service and the team behind it enough. Thank you guys so much! Markus
