    had to pay import duties, which was at first hard to figure out because DHL's site was not exactly user-friendly, but the seller contacted me a few times, telling me that the package was "on hold" ...so, thru persistence I did eventually prevail ;-0 I rated the condition of the item below based on the package, which I have yet to open, but it does seem really well packaged
