If you find yourself having insane input lag, here's your culprit. This app installs a hidden and horribly broken display device driver and does not uninstall when you remove the program or manually remove from the device manager. I had to do a system restore to remove whatever was left behind, and even still it left a registry startup entry trying to reinstall itself ("Kairos AiTemp\{FC61D62F-0DE1-4D91-A457-B3674ECE560C}") from the downloads folder if the installer file is still present! It also does not remove its firewall bypass entries when uninstalled. If you have to try it, create a system restore point and delete the installer immediately. I have serious sketchy vibes about this program. Google refused my $10 refund which was within 2 days and only minutes of app use to find it doesnt work with my Moto E5 Play.
