This device was purchased from the Hobbyist Miner and comes with some cool Gnome stickers. It has run flawlessly but I'm upgrading all of my home miners to Much larger ASIC and I need all of the power I can get. This device is very efficient and is water cooled. I've updated it to the latest firmware and it has a high and medium over clocking setting if you use the elphapex tool to download. I will preconfigure with your address and hash for free to your account for 24 hours prior to shipping to show you everything is working well. Please let me know if you have any questions.
