Agree they are terrible, not only do they tell you nothing about the item, aside from the fact that you are missing out by not owning it, they just blurt out a load of Innacurate rubbish. I've stopped bothering with things with Ai listings now. 
If people can't be bothered to tell you about the item I can't be bothered to message them and ask for an actual description. 

it's particularly bad for Vinyl records 

eBay should remove this option for descriptions in my opinion
