Just Mining is a french enterprise of a youbuter specialized in the cryptocurrencies world. This enterprise is growing in Europe. That the reason why they decided to add some product to their site. At the creation of this website, they sale 4 differents miners: the BOB (1 GPU) (I think this isn't the most profitable product), the double BOB (2 GPU), the super BOB (3 GPU) and the mega BOB (4GPU). The new product is the ExTra BOB (6 GPU)!!!! Hum... Why they don't make a 5 GPU ??? ;-) They have some cloud mining product too.
So you can buy this new 6 GPU miner ( if you can XD) here :
