I posted this issue before with not much feedbacks.
Anyway, bought Corsair and Redragon models to test. Corsair costs $50 but firmware is suck.
Redragon M908 is cheaper $34, and it works with RV, Photoshop n Adobe, etc. and it has distinct lighting choices.
I posted here the initial setup, just in case someone likes to do so.
Trick: remember to click "stop" button each time you done for one button setting.
I wish they have 2 or 3 more buttons.
