Not Writing … you can’t write to these, write error!
I could write on these, tried 4 different fobs from the batch keep getting write error. Used the ones I had lying around and I could write the data within a second. Imagine you ordered these T5577 125 low ID/frequency in emergency situation and you couldn’t write anything on them? These were ordered as a contingency measure should the ones at home played up, what a measure, these definitely failed to measure up!

Perfect for copying LF Access Tags
Why pay rip off prices charged by security companies when you can use these to make cheap copies.

Not writable
It can be read but not written. False advert UPDATE: Apparently for some reason only the Flipper Zero fails to write it but my other 125kHz writer managed to write it and then Flipper Zero could read that data back successfully... odd. My other 125kHz fobs can be read and written by the flipper zero. Not sure what happens here I would have to capture the spectrum and analyze I guess. Anyway as far as the product is concerned it worked out in the end.

Good when they work
These are great when they work unfortunately out of the 50 fobs only about half worked.

Fast delivery, and they work fine.
Tried these with an Arduino tag reader project, and with an N99 copier. These can be written multiple times.

Perfectas para el videoportero. Reescribíbles. Funcionan 10 de 10. Lo peor es que son todas azules en lugar de incluir colores variados.

Benutze die Tags mit einer Indexa-Alarmanlage. Da kostet ein RFID-Tag ~7€. Und der macht nicht mehr. Insofern kann ich die Dinger sehr empfehlen.

My building charges me $50 EACH for replacement fobs and my vacation home would only allow 4 fobs. These rewrite flawlessly and now I have ample fobs for myself and a number of friends as well.
