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.

In an industry full of mistrust and scammers, Altair is a shooting star of integrity and reliability; great prices, fast shipping, and excellent customer service before and after the sale.

Order a miner, everything was perfect. Service, delay of shipping, update on the shipping and tracking. The package was perfectly wrap. 5 stars
By Daniel C.
Great website, great product (Bitaxe miner), fast shipping, & great setup guide - was very easy to get up and running for someone who has no experience with BTC mining! All around, I'm impressed - keep up the great work!
