If you've gotten stuck standing or seated behind someone with these then you know the distraction is ridiculous! They may as well put a cast member with a flashlight in front of you and shine it in your eyes every couple of minutes!
I hate Glow with the Show ears!
I am a little intimidated by these things because I am not very quick with hand eye coordination and would not be able to keep up and have the ears turned to the right color like everyone else. It reminds me of playing "Simon" that light up game from the 70s.
I just don't need another gadget to learn. I have enough trouble understanding iPhones.
As for how the ears operate, from the wearer's perspective: the ears use AA batteries, and you turn them on and off by moving your finger over a small silver-colored circle underneath the right ear. Once the ears are on, they will blink randomly until you get in range of a Glow-enabled show, then the show programming will take over and control the blinking and colors of the ears.
The batteries burn out pretty quickly, within 6-8 hours, in my experience, so you can get one night in the park with them before you have to replace the batteries. Or just turn off the ears until it's showtime.
I'm quite surprised that Disney hasn't introduced a whole line of Glow with the Show ear designs. Having just one design for ANYTHING hasn't exactly been Disney merch's SOP for some time now.
