Its speed (3.2) simply left me speechless. It transfers files continuously and at high speed. There was never a connection problem with the laptop. Beautiful and compact device with normal weight. Although its price is considered high, it is the ultimate tool, especially for professionals.

Amazing build quality, with nice packaging, comes with two usb 3 & type c cables, for connection with all devices instantly recognizes the cards and transfers data almost at card's characteristics
Personally, I use cf express type A with speeds reaching 700 mb in reading, but also SD cards v90 again close to 300mb/sec.
If you don't use cf express cards there are cheaper solutions, because this one is extremely expensive for a card reader, if you want the best available you can buy it without a second thought.
*For me it is a essential gadget for those who are professionally involved in cinematography and photography.
