Multiple purchases made with Altair. All went smoothly. Have bought miners, cables, and even control boards. Doesn’t matter what it was, the transaction was flawless. Keep it up

Everything they promised and quoted they delivered. From ease of purchase, to the specs on the machines performance to the quick and easy setup.. My only issue was paying extra for express delivery and that not happening. But this was a UPS issue, not Altair's. They shipped it express, UPS did not execute a express delivery.

A prompt and professional handling of order. They are on top of their game. A new source for my equipment.

Great team. I had some issues with a Bitaxe sheath I purchased. They patiently tried to address the problem, and once it was apparent a replacement was needed, they promptly shipped it off. This all happened over 2 days. No BS, they fixed the problem. I’ll buy from them again.
