Ally Safety review for Theme Updater & Backups | OOTS

I have really liked my OOSB theme but this app and the support have been so bad that it has, unfortunately, really changed my view of Out of the Sandbox. Also, typically apps are priced based on their usefulness to the customer. How do justify charging $89 for an app that has low review ratings, poor functionality, and requires a significant amount of manual work on the customer's end?
