The package was delivered fast with no issues. I used the RFID chips with an automatic lock for a geocache I was building and each one I used worked with zero issues. Easiest thing is having the ability to have separate chips for anything I could use it for! Great deal!

Worked great, and a great value

The product was clean, easy to use, and accurate.

All FOBs worked well! Would definitely purchase again.

Worked great. They feel well built compared to other key fobs.

Works as expected. Great purchase
