I’ve got some tiles on my keys and my earbud case. I’m mostly pretty good with my keys (thy have hook hy the front door), but for the occasional time I’ve need to find them in a rush and they aren’t where they should be the tile has been very helpful. The ear bud one I use multiple times a week, and before I had it I’d regularly waste hours searching through my clothes and bags looking for my headphones (only to find that they fallen off the table and were now in a shoe or something).

So, if you’re prone to misplacing stuff they’re amazing. But if you never lose stuff then I doubt they’ll be very helpful.
