What is Reddit's opinion of FoxFi Key (supports PdaNet)?

From 3.5 billion Reddit comments

Unfortunately no, I Galaxy S9 recognized immediately what the app was trying to do and stopped it. Interestingly enough I was able to set it up inside the app and my laptop picked up and connected to the SSID I created, but it connected with "No Internet". I believe the mobile hotspot functionality of the S9 stopped it from working. Its the only educated guess I have. Also it requires you to purchase an additional "key" from an app called FoxFi for additional options
