Yes, I have one. I think they are the same in how they work. I have a couple other E2 boxes that are crap. The Edision boxes are excellent! The Viper 4K Combo, I have found to work just as good as the Edision.
You may be asking yourself, well why does he not carry this one? Well TBH, I have not had time to make it more North American friendly for the less experienced. If I started carrying them now, I would most likely be doing a lot of tech support.
But anyway, I like mine I switch back and forth between that and the Edision and can't find anything the other won't do. The wife likes the Amiko better because for what ever reason it runs the Kodi add-on much better, and she uses Kodi a lot.
