The restocking fees are typically waived in the event that there is a provable failure within the first 30 days and the warranty has not been voided by overclocking. In the event that you experience a failure, please reach out to the seller immediately so that we can begin troubleshooting with you and/or processing a replacement. 2. The AntMiner S15 includes everything you need EXCEPT for the following items: 2a. Ethernet cable to connect to your internet router. 2b. C13 Power Cable. The power cable you choose will depend on the type of power outlet you are connecting to. 3. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. 4. The S15 is VERY LOUD and sounds like a whiny vacuum. Returns due to noise will be subject to the maximum restocking fee. 5. Metal clanking or rattling is expected when moving the AntMiner S15. The sound is from the hashing boards moving back and forth against the metal frame. This does not mean there are loose parts and does not mean the item is defective.
