Isn't "undetectable" an overstatement? If you were a sophisticated attacker, you'd be able to detect RF coming from the Tiles every so often, right? Or do they only respond to the right signals from a signed-in device?<p>In addition, doesn't the anti-theft feature make it impossible to find the item if you aren't close with the proper Tile app signed into one login? The power of AirTags is that any IOS device can wander past, see the device, then send that info to the owner without the wanderer even knowing about the transaction. Tile was pretty restricted before as there are many, many times fewer Tile app users compared to AirTags. Now with this feature, instead of all Tile users being able to gather info, if the Tile isn't within a few feet of the one signed-in device, it's not going to find the Tile and the stolen item.<p>Seems like a thin layer of marketing slathered onto a product that isn't really competing anymore.
