I just received this (fake) Hakko FG-100 soldering iron tip thermometer. It arrived in just 11 days which is amazingly fast compared to other purchases I've made in ebay so far.

It seems to work well although I have not a means to compare the temperature reading (yet... awaiting

By the way... how can I put the attached photos in the text, not just at the end?
