Chip Power tuning box

Has anyone had any experience with the chip tuning boxes that are available via fleabay please? Just saw one which looks like a simple plug and play, are they effective, worth having? All help appreciated as always 👍.

110% not worth the plastic they come in.
You're better off spending it on a good service

They might work if your goal is to use more fuel.
