AirTags

If you plan on buying a couple of AirTags for a trip or keeping track of your stuff, then you shouldn’t have a problem with the current model.
They’re great and will help you find everything you usually lose. However, if you don’t have to buy them right away, you could probably wait, as there have been rumors that Apple will launch the next generation AirTags in 2025.
If the rumors are true, the new trackers will come with an improved Ultra Wideband chip to increase the distance you can track your AirTags.
Of course, since the AirTags are really affordable, you can buy one or two right now and wait until Apple launches the new ones to buy a couple more.
