I've ordered one head unit GM5154T from their main website (www.eonon.com). I've just received it today, can't tell you how good it is but I can confirm that custom tax and VAT was added by FEDEX (I'm living in Hungary). They indicated a lower price on the bill, so end of the day I just had to pay ~80USD extra. I've approched them via email, was no issue, they replied almost immediately. I read somewhere that their UK store is closed or will be closed so better to forget it.
