I use these as extensions for my PC Engine Controllers to play games such as Lords of Thunder and Rondo of Blood--no input lag at all! Cheap and essential if you're going to play PC Engine games on a big TV, since the original controllers have such short cords (similar to Super Famicom controllers) . Going to buy some more once I get my multi-tap. :)
Seriously, though. I bought five of these, and they've proven to be excellent extensions. Secure connections, no funny business with input delay or dropped inputs, works great with the multitap, et cetera. Wish they came in black, but otherwise, no complaints whatsoever.
I bought this as I was re-purposing an older set of speakers and the existing cable was not long enough to work on my desk. The cable arrived quickly and I was able to re-use my speakers. Good quality, excellent price and a perfect fit.
Works as a extension cord for PC Engine/TurboGrafx 16 controllers. No drop inputs, no input lag or anything like that. Really sturdy. Also works well with antiquated Apple computers. Can also be used to make custom connectors for a XRGB Framemeister Mini (in it's mini din 8 RGBs video port). But unfortunately it comes in 1980's beige.
PROS: Extension cord for: PC Engine/TurboGrafx 16 controllers Older Apple Computer Serial devices Some video devices
CONS: Does not improve my high scores on Gradius. Comes only in 1980's beige.
