What's so bad about Transplants in Turkey?

[Dav7]

For the past few months online I've heard a lot of people putting down Turkey for hair transplants, but I don't really get what the problem is? Yes they are cheap, very cheap in comparison to Western countries, but wouldn't this not be down to Turkey been a much cheaper country when it comes to pretty much anything. I just don't see the point of paying 10,000 for a transplant, when I could get the exact same procedure done in Istanbul for €2000. Help and advice much appreciated.
