I ordered ePoi Lite (they seem to work, they turn on, but are difficult to navigate through the modes. I can't comment on their performance yet).
What I was not aware was, that I must pay around 40% over my order for import tax on this product. This information would've maybe changed my mind.
However nor Emazinglights, nor DHL informed me to expect additional fees on international delivery (to Germany).
I just think that this information could've made it into some email (not the exact amount, but at least a warning).
Therefor I must rate 3 stars.
