A few days ago I send an email to email@example.com, because I bought a Mini Laser Engraving Machine 7000mW. I compared the laser module that you sent me with the laserax video of the 7000mW module and it is not the same module (attached images). The module that you sent me can not engraving
any type of metal.
I think you have to send me the correct module.
I'm waiting for your response.
