I tried the app to see if it makes my QA tasks easy. I can say the automated testing by the app is really good. This has saved me alot of time from the manual QA I used to do everyday. Its out of stock feature has also helped me get notified in realtime to take decisions on the inventory management. Highly recommended product for all the Shopify Owners out there. Just would like if they have referral program in future, so that I can get the benefit for sharing the app :)
