## Customer Reviews

### ⭐⭐⭐⭐⭐ Omnikey
*by R***E on April 13, 2026*

Very useful for making IST files!

### ⭐⭐⭐⭐⭐ Good product - works as advertised.
*by J***. on August 23, 2025*

The card reader works right out of the box, I would buy this again from this seller.

### ⭐⭐⭐⭐⭐ Accurate high speed smart card reader that works on Windows and Linux
*by H***K on November 22, 2019*

Very good product, much better than other smart card readers. Can require some effort to set up on some Linux distributions. Overall I can definitely recommend this product. The physical design of the product is also well made and will probably last a lot longer than other readers I've bought from other manufacturers. This product can also read full sized SIM cards for e.g. research purposes.
