Was a delay from the weather then once the weather cleared a couple days later then they sent me the KYC link adding another day delay after I paid for next day delivery. Why not send the KYC link while waiting on the weather delay???.

0 star – failed in 9 months, no meaningful support. I purchased a Bitaxe from Altair Technology. It ran hot early on (manageable with monitoring), but after about 9 months it stopped working. I contacted support and worked through troubleshooting steps, but nothing fixed it. They told me to ship it back for repair, which I did at my expense. After they received it, they told me the unit won’t even power on and they cannot repair it. No warranty coverage, no replacement, no credit. The outcome was essentially: “we can’t fix it,” and I’m out the product and the money. I’m not upset that electronics fail, that happens. I’m upset that when it failed, there was no meaningful support or resolution. If there’s no warranty, that should be made very clear at checkout, because the practical takeaway here is you may be buying a ~$200 device that can become a paperweight in under a year, plus you’re paying shipping to find out it’s unrepairable.
Response from Altair Technology LLCFeb 9, 2026
Hello, We’re sorry your Bitaxe failed and understand how frustrating that is. This is an open-source device that does not include a manufacturer warranty. Our 14-day functional warranty is clearly posted on the product page, at checkout, and on our warranty page. We include this warranty to ensure our customer receive a working device. We have even extended that warranty within reason when possible. Your order was however placed approximately a year ago, which is well outside that coverage. Even though it was out of warranty, we still offered to inspect the unit in good faith. After testing, we found it would not power on and could not be repaired in-house. We also provided third-party repair options. Unfortunately, we can’t offer a refund or replacement this far outside warranty. We’re happy to return the unit to you, ship it to a repair center (you must pay for shipping), or recycle it if you prefer. We stand by our clearly posted policies and always aim to support customers wherever reasonably possible. Thank you, Altair Technology
