Color is a problem, isn't it? Also, they have software and as soon as there's software, there's an explosion of over-complication that raises the minimum age limit for being able to use them.

This is a bit of a rant but I have a lamp/flashlight that my 4yo can't use because it's too complicated. It has 3 buttons which control 2 separate lights built into the same device. You can spend all day pressing buttons and making it change color or brightness or turn the flashlight part on and off but if you want to turn all the lights off, you have to know the secret button code. Also, one of the buttons is disguised as a USB port cover which looks the same as the other (!) USB port cover that isn't a button.
