The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
The support level of this app is gorgeous and really fast, that's why I decided to not only use the trial period but also to have it installed for good. I have to say however, that display and outlook is quite simple, nothing fancy, you are able to edit your CSS but of course you need to know about it. Apart from the simple design, the app really fulfills its job and if you have any trouble, the most amazing thing is the support team which for me counts really a lot.
