Outstanding Experience
The technician patiently walked me through choosing the right control board for one of my Antmines. The selections were very confusing he guided me through the process and made it very clear. Great service.

Altair went above and beyond to help with a miner I purchased back in December. Altair was able to get it working after hours of frustatration on my end. Honestly I would be giving 6 or 7 stars but I am not allowed so I will just say that AltAir deserves at least 6 stars, up to 6.75. Thank you AltAir.
