Second time ordering from BullMiners, this time the DragonBall. Mining rewards have been as expected. Packaging was okay, product arrived safely. Happy with my decision to go with BullMiners.

I upgraded from an older model to the DragonBall. Delivers exactly what’s on the spec sheet. Standard shipping time to Austria, nothing to complain about. Would recommend with small reservations.
