Q: Is the actual product the same as the product picture?

A: Due to the frequent replacement of mining machines, the manufacturer may modify the appearance and packaging of the machine without notice. Therefore, the goods you receive may not be exactly the same as the pictures and product descriptions. Please use the actual product you received. We will update the product description in time and ensure that the nominal computing power is accurate. Please forgive me for the inconvenience caused, thank you!
