I have started putting electrical tape over leds. My external sound card had the brightest white flashing light when the computer was off but the sound card is still plugged in. Impossible to sleep with that obnoxious white blinking.
Gaffer’s tape works better for me because its material properties and packaging make it suitable for a wider range of applications.
It handles many of my off label uses for electrical tape and duct tape. It is designed for versatility.
Every time I use good tape I know it was worth it. Good tapes just tape better.
If I need lots of tape, I am using the wrong tape and two or three rolls of the wrong tape is just more of wrong.
