What is the crowd's opinion of LEA Extended Input Gamepad?

From 3.5 billion comments

I wonder if LEA Extended Input Gamepad on a tablet would be useful?

There are other options for using a phone/tablet as a customizable controller. Maybe you can try them without investing any money.

One thing I do worry about is, if it requires a program on the PC, will it be detected as 'cheating' app? I don't know the answer to this one.

I use LEA Extended: Link to google play

I don't use keyboard at all, the best thing with LEA is once you have a profile you don't have to remember all keyboard shortcuts.

There's a better alternative to roccat

it can also use your old tablets and phones as extra control modules for ED or any game for that matter.
