Today I received my to units

They work beautifully!
I use them with a SEGA Genesis® 8-Button Arcade Pad - 2.4 GHz Wireless which I build into one of my Neo Geo fight sticks:



This project isn't 100% finished yet, but it works really nice! I personally does not feel any input lag, but I'm no professional... I'm a casual gamer
I also have some constructive critic, nothing big! You can ignore it if you like! The LED sticks out a bit too much. I was thinking about creating a 3D printed case for it, so I have to move it a bit back. I'll do this by myself, so no problem at all!!!
Thank you very much
@Raph_friend it is a really cool project
