Pros and cons
Pros
- Combines a card reader with 11 storage slots, which can help keep spare cards together while travelling.
- USB-C and the claimed USB-A adapter support connection to devices with either port type.
- Supports simultaneous reading for the combinations stated by the manufacturer.
Cons
- The simultaneous-reading feature excludes SD2+TF, so card-slot choice matters when transferring from two cards.

What to know before buying
Listing details to confirm
The 5 Gigabits Per Second listing is a stated transfer-rate figure, while the separate simultaneous-reading claim specifies 170MB/s. These are different claims and should not be treated as a guaranteed real-world transfer speed. The listing also names a USB-C-to-USB-A adapter and card ejector pin as included, but gives no explicit package inventory.
