Dust Fume Mists review for Matrixify

I have been working with Maris and his team with this App for 6 months...it has been amazing. 1. they are extremely responsive and helpful and also keep adding new capabilities to the app as we need them!!!! 2. The app - product, collections, Amazon, Google Shopping upload is extremely easy. Had 49k products to upload to one store and just under 10K for another store but they make it easier to upload than with the Shopify capability. And actually being able to sort out the collections whether smart or custom...priceless. 3. Updating products is easy and to make some products inactive - EASY! I know 'easy' is a buzz word here, but that is the only word that I can think of because after so many months of frustration - There was MARIS!
