I’ve only had mine for a few weeks but so far, they seem to work very similarly to the AirTag. They pair very easily and show up in the “Find My” app, indistinguishable to the AirTag.

Nice and stable for a good range of laptop sizes. Opens pretty wide and then closes well and keeps
it stable, even vertically!

I like this charger because it looks cool and it didn’t require extra add on adapters. It worked well for my trip to Italy and Germany. I would definitely recommend this product.
