I've traded some TF figures with him for the highly sought (by me at least... ) Convertors mini-spies and a Dino Rider figure. Everything came as described and well packed! Highly recommended trader, note that he has lots of non-TF toys for trade too, check his webshop.
EDIT: Since then I made numerous TF trades (2-3 times) with Fiski. Everything came as described, and he's a very generous (and patient!) guy. Highly recommended!
