Work fine for finding locally if in Bluetooth range. Not good for finding lost things outside of that. I lost some keys in July last year. Still not found since then.
Apples biggest benefit is the sheer number of phones that can help locate lost items. I was hoping Androids Find my Device network to be the same but currently it's really lacking.
I use nextdns on my network and there’s a filter there for smart tvs. Samsung seems to want to call home the most.
