Displayfusion Recenzje 

App is so slow it's unusable, it's full of bugs and not maintained. I wanted to support the app so I paid for it. Then I contacted support to report bugs. They ask for logs, I send it to them, i even record a video, then they proceed to ghost me and ignore all my follow-up requests. I was just trying to help you guys make this app better, but obviously you care only about the money, not the quality of service.

Simply put they advertise features that aren't implemented even after being requested 5 years ago, last update was under 1.5 years ago with "still in feature request list".
On their website if you go to "Free vs. Pro" tab and search for orientation, you will find they claim screen orientation is something their program can customize/change, which is a lie.
I installed it specifically for that, it's a feature i require as i have to switch orientations often and they advertised it.
I highly advise using the trial before giving them your money, as they might have other features that are falsely advertised besides the previously mentioned.
