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!

Works with Texecom Alarm
Bought a while ago, but none of these have missed a beat work everytimeUsed with texecom alarm systems as there tags are a bit different to others and worked all ok, Didnt work with paxton reader however

Not writable
It can be read but not written. False advertUPDATE: 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.

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

These are EM4100, not T5577 / EM4305
Could not clone from PAC/STANLEY card or T5577 cards onto this. These are EM4100 (confirmed by Proxmark and Flipper). They are emphatically not T5577 / EM4305.

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