  • Easy, fun and quiet. I like it.
Size: 1.2Th/s Black cooling fan
This is my first solo lottery mining unit. A also got a bitaxe after this one. This unit was pretty simple to set up and runs at a consistently higher hash rate than the bitaxe. It's quiet and fun to use. Works as a swarm with other same brand units. I don't know of I'll hit a block but why not give it a shot. You miss all the shots you don't take. ... show more

  • Great little lottery miner that anyone can tinker with.
Size: 1.2Th/s Black cooling fan
Fun, easy to setup and connect to wifi and the mining network. Great educational item to learn with for beginners. Unit performs as stated and expected. Very quiet and low cost to operate, just pennies a day. Unit consumes low power so it does not produce a lot of heat like other units.

  • Miner with a nice looking frame
Size: 1.2Th/s Black cooling fan
The clear plastic frame looks nice but the protective film is tricky to remove. I found that rubbing a credit card along the edge raised the film enough to grab it and pull it off.

  • Low power consumption and quiet.
Size: 1.2Th/s Black cooling fan
I received this little mining rig fast packaged very well. Simple and efficient little powerhouse! Looks really cool and it's not loud at all. Runs smooth! Set up wasn't terrible but I have some experience so for someone new to solo mining they may need to watch an instructional video. Great mining machine! ... show more
