Warranty & Support

Warranty & Technical Support

We want your mining journey to be successful. At Calvin Rig, we stand behind the quality of our Bitcoin solo miners and are committed to providing top-tier technical assistance to keep your rigs hashing smoothly.

1. Technical Support & Setup Assistance
Every purchase includes access to our technical support. If you encounter difficulties setting up your Bitcoin Solo Miner, we offer remote consultations to ensure your equipment is hashing correctly and connected to your chosen pools.

2. Limited Hardware Warranty
We provide limited hardware warranties for our physical computing nodes. The exact duration and service network (e.g., 3-Month Local Warranty vs. 12-Month Factory Warranty) depend strictly on the specific product model and the Service Tier (Standard or Premium Edition) selected at the time of purchase. Please refer to the specific product page for your exact coverage details.

3. Coverage Details & Logistics

• Labor & Diagnosis: This warranty covers the labor and diagnostic fees required to troubleshoot and repair manufacturer defects under normal operating conditions.
• Replacement Parts: The cost of any replacement parts (e.g., ASIC chips, control boards, screens, or fans) is excluded from our local warranty and will be invoiced to the customer separately, unless covered under the manufacturer's original factory warranty.
• Shipping Fees: Customers are responsible for the two-way shipping costs to the designated repair center (Local or Asian facility).
• Cross-border Logistics: Any cross-border administrative fees (such as the US$150 VIP Logistics Concierge fee for Asian factory routing) will be applied or waived strictly based on the Service Tier purchased, as stated on the product page.

4. Warranty Exclusions
To maintain your warranty coverage, please operate your miners within factory specifications. The warranty is strictly voided by overclocking, installation of custom/third-party firmware, improper power supply/voltage, physical damage, water damage, or unauthorized disassembly.

5. Certified Hardware Guarantee (Safety & Reliability)
Many hardware failures and fire hazards in the mining industry are caused by cheap, uncertified power adapters provided by overseas drop-shippers. Every Calvin Rig miner is shipped with a globally certified Power Supply (CE, FCC, cULus, UKCA, PSE). This guarantees a stable voltage supply to your miner, maximizing its lifespan and ensuring 100% safe operation in your home.
