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.

Not gen2 CUID
These are gen1, you cannot change UID with MCT.

Excellent value
These are excellent value mifare tokens. The only tiny thing that sometimes lets them down is the second tiny link that connects the large ring to the token

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.
