I haven't any issues with them, and I've had them for years. In fact, they were the foundation of my smart home setup, and continue to be central.

They worked fine with the ConBee 2, and work fine with the ZBT-1 that replaced it.

That said, they're used within a relatively small area, and have direct connection to the coordinator. My one (major) annoyance with them is how hard it is to open the battery compartment, the plastic is too soft.

I've since added some Sonoff T+H sensors which are fine, though twice as big.

My one disappointment is the Arre (Thread) sensor, which has low resolution and bad battery life.
