I had an issue with the shipment of my new BitAxe, the display was unseated ... Kris, the service dude, worked really patiently and accurately with me. Up and running and love my new Blue BitAxe

I ordered this Bitaxe Gamma on Saturday and it arrived Thursday Memorial Day week. That was fast and the setup was easy and simple I’m looking forward to grabbing the NerdQAxe coming soon too. Thanks 👍🏾
