I remember getting a guitar pedal for Christmas when I was like 16 or so. My dad did not believe me that you were supposed to step on them, and was angry at me for mistreating his gift, lol. I showed him footage of real bands doing that and he told me "Yeah and Hendrix used to light his guitar on fire on stage, but you're not doing that either." He thought it was a stage trick.
A well made pedal does feel great though. I still have a Boss pedal from 1988 that works with no repairs. Wish all of them were that durable, the DL4 is notable for having connections come apart internally after about a year. Easy fix, but sucks if it happens on stage.
Point #3 is a big deal, especially being easily readable on stage in no light or lights in your face. I have the Lillian Phaser pictured in #5 and had to put tape over the blue LEDs because they are so bright they blind you when you look down. This isn't an issue specific to the Lillian either. From what I understand, blue LEDs are much brighter than the rest, and most designers don't take any steps to dim them.
