Compatible with Aqara U200
works perfectly with Aqara U200. An idea is use it for contractors and once the job is done, delete the user from the Aqara app so security is not compromised.

Overall good
These fobs are as described. Block zero (0) is 100% rewriteable, that does include the UID. I was trying to rewrite these with some software I wrote myself wondering why it wasn't working at first but I also learned that these Chinese-made fobs need a certain "unofficial" sequence of bytes sent to it in order to unlock block zero which are in fact used in certain libraries. Once I figured that needed to be done I was able to write whatever data to it I wanted. Unfortunately I had to knock off a star since the build quality wasn't great. The clam shell design of the case came apart quite easily and the little disc inside containing the chip could fall out. I think they just click together with not much holding strength so I pre-emptively took them apart and actually glued the insides together before deploying them. Other than that, they work as expected.

Perfect
Works brilliantly for a great price

Not writable from (unrooted) Android
These tags appear to need special commands sent, not a standard Mifare block 0 write and so none of the (many) NFC apps I tried on a Pixel 3 XL were able to write to block 0.

Perfect 13.56MHz tag
UID is changable multiple times. Whole tag is rewritable (as long as you do not lock it) These are Chinese Magic Gen1 Perfect for making a 100% clone of an existing tag.

no me funciono
no fueron compatibles con otros llaveros identicos. supongo que es por la frecuencia que manejan.

UID MODIFIABLE (Block 0)
Yep, I could actually modify the UID (block zero) and clone a key that I had lost.

Dessa taggar fungerar inte, inte en enda.
Idag fick jag min apparat iCopy 5, så kollade på Youtube lite klipp hur man använder och kopierar taggar och kort. Testade en efter en och ingen av taggar som fungerar, hade en tag sen tidigare köp av min kollega den tagen fungerar som den ska, fick 6 st, kort med apparaten i lådan dem kort fungerar klockrent, men dessa som jag köpte från Amazon.se fungerar inte, mycket bisfiken faktiskt.
