Review on 📸 Enhanced SanDisk SD UHS-I Card Reader for Optimal Performance - Model SDDR-C531-GNANN by Paul Ajayi

I bought this because I have two new Sandisk Extreme Pro 170MB/s cards. Sandisk says you have to have this card reader for these cards if you want this kind of speed. I only get 30MB/s on both cards. Like other cards I have, all Sandisk Extreme cards. This device is read-only. You cannot transfer data from a computer to the card. only from the card to the computer. Inside the reader is a pull tab (visible with a flashlight) that locks the card so you cannot write to or format it with this reader. This tab also unlocks the map when you drag it. It is extremely difficult to insert a card and just as difficult to extract it. My Kingston reader/writer is just as fast and has slots for all types of cards. I do not recommend this reader and will not buy it again.
