You can tell if you have a clone box , as there will be a sticker on the back or underneath, the sticker will be V2.0 or V3.0, you may also have a sticker on front top left directing thou to a website for software, also they are slow to boot, and remote is not as good as original.
I agree that the solo is now over rated, I'd recommend a unibox hd1 plus (from our sponsor), for the same money you get 2 x sat tuners, and a lot faster box, you won't have blackhole image though, but openvix has now become my favourite image over blackhole.
Plus clones are bad for the good people who make the originals. Think of it like this, most people have bought a fake watch, it lasts until you get home from your holiday and then it stops, and you throw it away.
