Order a miner, everything was perfect. Service, delay of shipping, update on the shipping and tracking. The package was perfectly wrap. 5 stars
By Daniel C.
Great website, great product (Bitaxe miner), fast shipping, & great setup guide - was very easy to get up and running for someone who has no experience with BTC mining! All around, I'm impressed - keep up the great work!
