Easy setup, works and connects properly.
Big downside is that the battery runs out very quickly to the point that it becomes annoying (you have to charge the card with a wireless charger – if you don’t have one, you’re out of luck) and there are no instructions on how to turn it off or, if it turns off, how to turn it back on so you can reset it (reminds you of what we call a "rip-off")!

Pros:
-Works perfectly and is easily adjustable
-Its price is reasonable (when I bought it €20)

Cons:
-Its thickness is about 2-3 credit cards (makes sense but still a negative)

I've been using it for about a month(?) and I'm waiting to see what happens with wireless charging

It had fallen off while I was riding my motorcycle and I hadn't noticed (I had it under the motorcycle seat for tracking and it slipped out through gaps in the frame). I went and picked it up more than a month later at the spot where it showed it was located and found it thrown among dry grass, in an area that during that month had a heatwave (37-42 degrees) and heavy rains. Nevertheless, the GPS, Bluetooth, charging magnet, button, and speaker all worked normally and without any loss of performance.

Very convenient card. Until recently, I was forced to use an AirTag, but now it's no longer necessary for obvious reasons. I recommend it! (Also, the fact that it charges wirelessly makes it even better)

Amazing product, it does exactly what it promises with ease and comfort without unnecessary charges. The best thing I have bought in recent years.

It does what it claims, but the non-replaceable battery makes it single-use – therefore not particularly useful. It didn't last even 5 months.

I have had it for a few months, there doesn't seem to be any problem, they work perfectly and the size is just right for a wallet. Something worth noting is that because they don't have the Apple chip, while they appear normally on the map, you can't locate them accurately within the space. Nevertheless, the sound produced by the built-in speaker is quite penetrating, so it somewhat compensates for this lack.

Very good. Very practical. One very small flaw for me: it is thicker than a credit card, resulting in having to take out 2-3 cards from my RFID wallet. Not such a big minus for me.

It does exactly what it says. The location is more than accurate. Every time someone passes by with an iPhone, it gets a signal and the exact time. I definitely recommend it.

It does exactly what it says, hidden behind the ID in the wallet and you feel calm, even if you move away from your things, you get a notification from Find My.
Very convenient that it is in card form and its speaker sounds good even if it is inside the wallet which is inside the bag!
I recommend it!
