I have them and don't really like them (I assume you mean the Thread ones). Battery life is mediocre, worse than coin cell operated Sonoff Zigbee one I have, accuracy is good, but you can't set update rate or threshold or any generally advanced feature.

Sometimes they either stop updating or drop off the network permanently.

I wouldn't really trust them for anything even remotely important.

Shame since they're pretty cheap, perhaps they'll fix the firmware and then they'll be excellent.
