YARONG-1PC waterpoof Writable rewrite 125khz duplicator silicone rfid T5577 wristband

This worked great on the first try duplicating a 125 kHz RFID fob. This bracelet lets me open doors with my hands full which eliminates the need to fish my key chain and the fob out of my pocket. It programmed in seconds using a Flipper Zero. Very pleased with this.It is advertised as being 60mm (considered "Adult") in size. I did not measure it, but I am a 160 pound male of average build, and it fits my wrist just perfectly with no room to spare. It is comfortable and not tight on my wrist, but also does not have any slack space. In my case, the fit is perfect because it allows me to pull sleeves over it without the bracelet moving around and without it being difficult to bring my shirt sleeve over it.

Ordered for RFID project. I've been working on RFID for years and have multiple readers at multiple frequencies and couldn't get this bracelet to work. Really wish it did work.
