SCAM
Checked the functionality of my device in various ways before sending it in. Sent it in, was told the device wouldn’t power on. Asked for them to send it back (which they guarantee they can), was fed a spoonful about how shipping it back was unethical due to carbon emissions, etc. Demanded they send it back. Received it, it worked completely fine. Told them as much and they never replied. Confident that they were trying to rip me off and refurbish it for money.
