Hmm...lets see.. I've been using tile for 5+ years...they work 50% of the time, the other 50%, Tile is telling me I need to replace the tile I just bought yesterday.So how are these better than Tiles? I love my tiles including my slim which fits in my wallet.
Not to mention the unwanted "rings" of my phone because a tile got bumped, or looked at sideways.
User replaceable batter is a win. Yes tile has them too...and they work about half as often as the non-replaceable.
If airtags are even a marginal improvement, Tile will be dead to me.
