Wanted to mine LTC and noticed that Unigrade had the Litecoin Miner L7, decided to get myself one. Received it within a few days of ordering (First time purchasing here). The mining rig is incredibly powerful, gets me a good amount of hash power and a good amount of noise power lol. And I'm confident that this ASIC will probably last me for years, and while LTC "may not be profitable" atm, once it is, ill be ahead of the curve. Regarding Unigrade, everything was super smooth, from purchase to delivery.
