I bought previous version (2020, micro USB) and bought it for test. It's almost same features but more better speed but no space to contain program in reader NAND. Reader NAND only partitioned 10KB to store only URL to download nfcPro wbw 2021 version windows application. ( no other OS support ) Working fine for my all 13.5MHz RFID cards as well. USB type C is more comfort to use, and gives more durability. Fine.

Unencrypted keys 125 kHz and 13.56 MHz reads and writes well. Crypto-keys for NFC 13.56 MHz picks up long and not always successful. Built-in USB disk is only 12 KB (although I saw on the Internet photos, where it is 2 MB in size and there is an executable program). The link in USB disk is correct-to the latest version of the program. In general, the device is working. I recommend the goods and the seller.

Checked the device for reading and copying keys and cards to 125 kHz: Excellent. Latest version of the 2021.09.22 app . 01 is quite workable. The only drawback of the device is the lack of mobility (attachment to the PC), but autonomous programmers and cost more. Thanks to the manufacturer and seller!

Bomb. With the intercom works, with the cards of arrival from different institutions works, all recognizes. On the device itself there is no program, only the link to it. I did everything on Win10, writes and reads. It takes a couple of seconds.

The product is working. Link when connecting a duplicator to the latest version of the program. Made a duplicate key chain from the doorphone and school card. The keychains in the kit are similar to 13 MHz, did not copy to the intercom.
