Quite a lot of deserved hate, honestly.
1. Almost all are "appified", aka proprietary crappy BT protocol with required corporate spy/app.
2. Non-replaceable LEDs means burnout = e-waste.
3. LEDs are overdriven meaning they're intentionally ran to burn out sooner.
4. Many of the "fans" are indeed blades on a motor. For they blow? Nope. But they do indeed suck.
5. Many are just hideous and garish pieces of garbage. But "in matters of taste, the customer is always right".
