First off, If I'm right, anything that has the number "510" written on it, will fit onto your eGo or Tornado Battery
But I may stand corrected on this one
There's a pro coming shortly, I think
About the shipment. Here in DK we have a rule, that we can trade with any EU country we want to, with out costums going crazy - but if I order from the US, costums will go nuts over my packages.
I know that Germany is part of the EU, so depending on the rules of Slovenia, you should have no problem ordering from the UK or the German site
As far as I know, anyways
Have a good one, and I hope you get the stuff you want
