I’ve had Chipolo trackers for 3+ years and Tile trackers (the ones with replaceable batteries) for over 6. No issues with any of them. You change the battery when needed, and you’re good.

Side story: My Garmin heart rate monitor finally had its battery changed… well over a year later. I’m looking at new models to compare, and they all have built-in, rechargeable batteries that last a whole two months! 🙄
