My wife loves her flip. She just upgraded from the 4 to the 6 and the creaae is barely visible when in use
She uses it a lot for videocalls and she folds it to use it as a tripod, and also being able to use the good camera to take selfies is a great use case
She also loves that it fits on most of her pants when folded, usually women’s pants have very small pockets.
That phone is not for me, but I can definitely attest to real use cases
There were cheaper ones with a tester attached to the box, maybe they were energizer?
