You'll need these so you're not sitting right up against the TV, especially since TVs are much larger and brighter than 30 years ago. Your mom told you that was bad. The NES Classic is especially troublesome with only 3 foot long cables. These give me the length to sit comfortably at a distance on the couch and play, though I still need to get up to hit the reset button to save state. Useful for the SNES Classic, too, despite its slightly longer 5 foot cable length. I use one cable for each of the two systems so I don't have to keep exchanging a single cable between them. No distinguishable signal delay or other performance penalties incurred by use. Well worth the price.
