Good communication and fast shipping.

I've just received my Bitaxe from Altair (I chose the Gamma version for its Noctua fan, the Rolls in this field). The manufacturing is of great quality. The machine runs at 1.1 Th/s for a power consumption of 20W, which matches exactly the manufacturer's specifications. I had a problem at start-up (but it was my fault) and the support was extremely reactive, the config problem was quickly solved. In short, I highly recommend Altair Technology, both for the quality of their products and the efficiency of their customer support, an excellent experience.

Received my miner quick! It was on back order, but it didn’t seem like it! Will definitely look into another miner when I can!

New to mining. Referral from VoskCoin YouTube channel. BitAxe Gamma received quickly, excellent condition, and essentially plug and play. Perfect for a noob. TY
