Functional cheap enough
As described, a tad overpriced, length is good, the end crimps very easily so it doesn't last long, does get warm when you touch it after a long time plugged in, it's functional, we bought several of the same in the past they've all had the same story functional get a little warm the middle part on hooks easily, which does make it hard when you're trying to charge something
