Miner swapping scam? How to deal with and avoid becoming a victim?

Antminer DR3 turns into A3 after being powered on. This is called an "item swapping scam", which usually involves a third party, who exchanges new miners with other miners or unprofitable miners, and then sells them as new miners.

In order to protect yourself from such scams, please note:

Know and check miners before purchase

Most miners may look similar, but if you look closely, they are definitely different.
