## Customer Reviews

### ⭐⭐⭐⭐⭐ very good low frequency fobs
*by D***. on July 3, 2024*

Program them with a proxmark 3 easy and they always work. These are the real deal.

### ⭐⭐⭐⭐⭐ The Real Deal! These are the ones you are searching for!
*by J***. on May 4, 2023*

After getting a RFID writer and receiving tags with the machine that look vertically identical I was very skeptical. These worked to copy 125KHz without a hitch. I alkways manage to lose the key to my GYM, now I have several back ups!

### ⭐⭐⭐⭐⭐ Great T5577 clones, writable traceability blocks
*by D***N on January 12, 2024*

These are great T5577 clones with unlocked traceability blocks that you can modify, meaning you can use these with Keysy or Mr. KeyFob writers if you can rewrite blocks 1 and 2 on Page 1 to be something those writer's DRM will validate. (I used a Proxmark 3 Easy).They ship preconfigured to emulate an EM 410x with the ID 0000001450. I've only tested cloning EM 4305 tags and that worked fine, I imagine all other emulations will work fine as well.I will buy again.
