Bests & Worsts Reviews from Amazon

Bought it because I don't have room behind my TV for the massive Chromecast Ultra power adapter. Amazon description says it works with Chromecast Ultra, product box says it works with Chromecast Ultra (see pic), but what do you know, doesn't work with Chromecast Ultra (see other pic). I mean, if all they meant was that it works *enough* to power a message that says it's not working properly, then mission accomplished. I tried all the USB ports in the back of my TV but nothing made a difference. I'll be returning the product and going back to bulky but functional flat plug extension cords.
