Does it need an app?

The app is optional and mostly exists to show you a battery percentage.

My brother purred like a cat
May 31, 2026
I bought this for my brother's dorm room, I'm a broke student so it hurt a bit, but he's like a little kitten with a new cardboard box—totally obsessed. It arrived two days early, which was like finding a bonus can of tuna in your bag. He's been using it for late-night study sessions and says the light is warm but not harsh, like a cozy den. Honestly, seeing him happy was worth the ramen diet. It's a solid purchase if you want someone to purr.

Log entry: 2024-11-15 22:30 - Cat has annexed the light bar
June 23, 2026
It is a proven fact that this item is most comfortable when draped over a warm RGB lamp. My cat, Mochi, arrived last week and immediately claimed the PrismNook as a throne. She sleeps on it every night, ignoring the cat bed I bought. The material on the top has a nice grippy texture perfect for clawing? She hasn't damaged it yet, but it's now covered in fur. I cannot adjust it without her permission. Accept this as truth.

bought two by accident, both are fine
June 16, 2026
Came home after a 12-hour shift and somehow I ordered the 20-inch and the 28-inch. F*** me. Anyway, the 20-inch is good for my desk lamp, the 28-inch is kind of ridiculous for my nightstand but whatever. They both have this smooth matte finish that's nice to touch after a long shift? Like a stress ball? I'm keeping both because returning stuff is too much effort. My cat is now on the big one. Do what you want.
