Thank you for the 5-star review! We’re glad the ordering and payment process was easy and that your miner arrived on time and in perfect condition. We appreciate your support! Altair Technology
The box for the power supply works great! Little hangers in there and on the side down from the print, but not a deal breaker. It will do just as I need it to do. Thanks!

They stuck with me to get my NerdQaxe++ back up and running (bad PSU). Well done!

Thank you for the awesome 5-star review! We’re glad we could help get your NerdQaxe++ back up and running. Troubleshooting issues like a bad PSU can be frustrating, so we’re happy our team could stick with you and see it through. Thanks for the kind words and your support! Altair Technology
Kris is very responsive to emails when you have an issue with your order. I placed one order and didn’t get it after a week of waiting. Sent him an email and got a response the next morning replacing my order and received it two days later in the mail. I proceeded to place another order for a miner after receiving my first package, product was shipped out the same day and received to days later on the east coast. Would highly recommend purchasing from this company to anyone!

Thank you so much for the 5-star review! We really appreciate you sharing your experience. We know how frustrating order issues can be, so we’re glad we were able to resolve it quickly and get everything delivered without further delay. Thank you for your trust and for coming back to place another order, it truly means a lot. We appreciate the recommendation and look forward to supporting you again in the future! Altair Technology
Kris and the whole team at Altair make an amazing product and are very responsive to any issues I have. I had to update my Mailing Address after my order had been completed, and Kris was on it within minutes. My product looks beautiful and is a great addition to my home. I purchased a BitChimney which I use to heat my basement, and it is fashionable while also warming a roughly 1000 daft space without being burdensomely loud. My wife and I can comfortably watch TV next to it. Extremely pleased with their service and I’ll certainly be a repeat customer!

Thank you so much for the great Review! We truly appreciate you taking the time to share your experience. It means a lot to hear that our team was able to jump in quickly and make the address update seamless, that level of responsiveness is something we take seriously. We’re also thrilled that you’re enjoying the BitChimney. Hearing that it’s both heating your space effectively and fitting comfortably into your home (and passing the wife approval test 😉) is exactly what we love to see. Thank you for trusting Altair Technology and for your support. We’re grateful to have you as part of the community and look forward to working with you again!
