Pretty satisfied with the DragonBall. Easy to set up and configure for my pool. Legitimate business with fair pricing. Only took a little time to find the right pool settings.

The DragonBall works great for mining crypto. Runs quiet for a miner of this caliber. I had to update the firmware on arrival. Overall a good buy from BullMiners.
