8BitDo Mod Kit for Original NES Controller（Original）

It works excellent,its amazing getting to use old antique controller with new hardware wireless :)

I recently purchased a mod for NES, SNES, Mega Drive, Saturn, and N64, and they've all worked perfectly, except for this NES mod. The product works without any issues. The blue LED lights up, but when I try to load it, the red LED doesn't. I don't know why this happens; I've reinstalled it about four times, but the result is the same: it works, but the red LED doesn't light up.

Great little hack, assembly was a breeze, works flawlessly (after some minor Retroarch configuration hassles)!

My NES mod kit works as intended. Easy assembly, no fuss, no headache. Love it. Buen producto. Thank you!-)

I have these on two of my original nes controllers and have them paired to an NES Hub in my vintage NES. I haven't noticed any lag, only complaint is the usual delay when turning on the console before it detects the controller, but that's a small price to pay for the convenience.
