I have a handful of Aqara motion sensors because some idiots on Youtube recommended them. They're shit compared to the Hue motion sensors though, and take 3+ seconds to respond while I look like an idiot waving my hands around and sometimes even need to take off my shirt and wave it like a flag to get the lights to turn on. The Hue motion sensors respond almost instantly in comparison.

All this low power electronics designed to run 3 years on a coin battery bothers me. If it's that low power why not get rid of the battery, slap a tiny solar panel (the kind they used on calculators in the 90s) and a supercapacitor, it should be able to power itself indefinitely on normal levels of room light, never go into deep sleep states, and can even turn the room lights on automatically if it needs more power.
