Salut je suis satisfait se très rapide bonne qualité

Tested on USB 3.2 port with a CFExpress type B of up to 1700 MB/s. reading. In file transfer it reached an average of 460 MB/s. The previous USB 3.0 reader of 10 Gb/s. for SD (non CFExpress) cards reached 90 MB/s. When inserting the reader for the first time in Win10, I got a message about possible Thunderbolt mismatches. As it is USB 4.0, it must be compatible with Thunderbolt. USB 4.0 compatible with Thunderbolt 40 Gb/s. Totally satisfied with the product. I recommend it. Entrega：Ordered on January 2nd and received on January 13th. Total 11 days from one side of the world to the other. Great logistics from this seller. Calidad：  It seems to be a good quality product, very well built, within current standards, and it can also be assumed to will have a good durability.
