I do agree they are complete crap starting at the Tone Arm and working both ways from there.
Lousy Cartridges, way too much force on the needle cutting into the Vinyl way too much Wow & Flutter and that's all before it even gets to any sort of Signal Processing.
I personally wouldn't touch anything like that, but way too many people do and they have no idea of what it is that they are listening to.
