Great to deal with - fast shipping and best pricing. finally a legitimate USA bitcoin hardware vendor. Crypto is a cray place, but the Altair team is the best to work with. Have bought from them multiple times.

Great Customer service! Bought a few miners from them now and they go above and beyond helping anyway they can.

Quick shoutout @altair_tech for becoming my favorite and go-to supplier of all things Bitcoin mining. Whether you are looking for a solo miner to get started or need any and all parts for larger Antminer set-ups, they have it! Not only that but they have some unique and fun modified iterations of Antminer in the Urlacher and BitChimney. I’m always excited to go to their website and check out what’s new. Lastly but not least, the service is impeccable. Quick responses and so very reasonable on customer requests. Please buy from @altair_tech !

The Bitaxe cases just arrived, and I couldn't be more impressed. The quality, service, communication, and pricing are all top-notch—truly above board. Thank you for consistently being our go-to source for must-have items. You should be proud of the level of excellence you deliver!

Not only is the product 5 star (I have two), but I received email customer service even when out of warranty. One device had a setting revised (my own error somehow) and Altair spotted it immediately. I adjusted and all is working perfectly again.

I received the bitaxe in six business days. The service before the sale was efficient, I had my questions answered, so I paid the import fees and courier in advance when I bought it, I saved money and it arrived quickly. The product works well, volts at 1060, above that it gets hot, but it continues at the advertised speed. It came with the cover, although I didn't ask for it. I'm happy with the purchase, I hope it's my lucky bitaxe.

Altair shipped a.control board for an s19k pro on time and well packaged. Also the correct firmware for my miner was loaded, so all i had to do was plug and play. I was mining within 30 mins, thanks!
