Okay, I've been a Tile guy for a while.  I liked Tile, first on the market, got a lot of traction out there, and for us Android folks it was the only option out there. I had a regular old 'tile' and I had a few of them set up on my keychain and my wife's and my kid's.  But... The battery would die (and it's a $16 battery) about every 6 months.  Then if I didn't set up the Tile app on my newer phone when I'd get it, it didn't really help me (see usually I was using the Tile to find my phone).  I liked how I could integrate Tile with my Google Home, so I could ask my Google Assistant to find my car keys... Handy stuff. The drawback unfortunately with Tile was that it's only as good if you have a lot of other Tile users around.  When it first came out, it was nice to see Tiles everywhere, then you knew that if I had left my keys at a restaurant, then when I would be somewhere far enough away, I'd need to have people with Tile near where my keys ...
