Excellent
LED addressable via MSI Mystic Light,
A molex cable is supplied with the led strip, but check that a 4 pin cable (12V/r/g/b) is supplied with your motherboard (included with mine: MSI MPG Z390I GAMING EDGE AC).
The magnets do their job, no double-sided tape provided.
The headbands are designed to clip together (clip provided).
You can buy with your eyes closed ..... or there is Corsair but it is more expensive!
