Thanks for your answer ... In the past I had trouble with the inputlag that bluetooth gave me (both internal bluetooth from raspbery pi 3b and a good asus bluetooth dongle) and my personal experience is that RF dongle gives me a lower input lag ... Don't you notice any difference?
About the wiiu pro controller: it's the best controller I have ever had I think, but the dumb f*ck I am, I sold it with my wiiu lasat year. I really regret that ... About that chinese copy: is the battery the same? because I like the 80hours from the orginal!! And what about the inputlag?
I now bought a CLS wireless gamepad (rf) it's great for the price but now I'm not sure anymore that it has lower inputlag then bluetooth ... maybe I had a bad dongle or something ...
SO if someone knows a good controller with THE BEST RESPONSE , please let me know
Thanks in advance!!
