▸How to ship your hardware
📍Ship to: Antminer Repair LLC, 2141 NE 51st Ct, Apt E, Ft. Lauderdale, FL 33308
📝Put a printed note inside the box — your name or company, return address, phone and email. Without it the repair can stall.
🫧Hashboards: at least 8 layers of bubble wrap on every side, reinforced corners, sturdy sealed box. No sealed air pillows — they burst in transit.
📦Whole miners: original packaging with foam inserts if you have it. No cables or accessories — anything that is not packing material is not returned.
📨After shipping send us the tracking number, package weight and dimensions.
⚠️Damage caused by improper packing is not covered by the warranty.
