Thoughts on nerd miner v2 pro

Came across the nerd miner v2 pro on ebay and the price seems alright. Just wondering what you all think about it and if it's a good idea to invest 4 or 5 to start mining.

If I'm not mistaken, the hashrate is ridiculous, in the order of a few kh/s isn't it? If you're interested in lottery mining, I would recommend Gekkoscience's ASICs. You will find some USB ASICs doing up to 300 GH/s and more, or in the Th/s 's range with the R606 - R909. You can find them online and they are not too expensive. Gekkoscience's ASICs are stable, reliable, and made their proofs since years. A (very very lucky) block was already found by a USB Compac F. Otherwise, Bitaxe is a open source ASIC project and some are on sale (already assembled I mean) if you look at their topic on the forum. It will be more efficient than nerd miners too , but the project is pretty recent. (I think that for now they deliver only to the US) In any case, the chances of solving a block are tiny, but at least you'll have a small chance, because with a few Kh/s it's almost non-existent. The forum is full of information on this subject, you can search in the Mining section and you'll find all the info you need on lottery mining, and small ASICs.
