This Blackmagic Design ATEM 1 M/E Production Switcher doesn't come with a power supply. It has a couple of known issues: several heat sink panels are bent and the Input 1 HDMI doesn't work.

Using this switcher? First, you'll need to get your own power supply as it's not included. When setting it up, be aware that the Input 1 HDMI won't function, so use other input options. Regarding the bent heat sink panels, keep an eye on the device's temperature during use. If it seems to be getting too hot, you might want to take a break to prevent overheating. For maintenance, just keep it clean and dust - free. Wipe it down gently with a soft, dry cloth from time to time.
