Both Micro and SD cards are Both recognized to read and write!
This adapter is great! It recognizes both the Micro and SD cards at the same time. It allows me to connect it to my usb-C port which is noticeable quicker than my USB 3.2 port( which is still quicker than my USB 2 port)I use this adapter to move video files from my Laptop and my local network. And this adapter does it beautifully.This adapter has both Usb3 A and Usb-CI would definitely recommend this adapter!

    I love the dual slots that allow me to read both SD and Micro SD cards simultaneously, saving me time and making multitasking a breeze. The USB 3.0 speeds ensure that data transfers are lightning-fast, which is essential for large photo libraries and important documents. Plus, the sleek design fits perfectly with my MacBook Pro and Chromebook, adding a touch of elegance to my tech setup.

    However, while it’s compatible with a wide range of devices, occasionally switching between different operating systems can require a quick restart to ensure proper recognition. Additionally, the small size means it’s easy to misplace, so keeping it in a designated spot is essential.

    Overall, the uni SD Card Reader is a must-have accessory for anyone who needs reliable and fast data transfer between memory cards and their devices. It’s versatile, efficient, and seamlessly integrates with multiple platforms, making it an indispensable tool in my digital arsenal. A solid 5-star rating for its speed and compatibility, with a tiny star lost to its easily misplaced nature.

    I liked the smaller form factor versus the old Sandisk ImageMate All-In-One workhorse model that is intended for a desktop setup. I had no issues with the Uni USB-C reading Samsung or San Disk memory cards. Uni functioned perfectly via port to port read and write at simultaneously and from card to card data transfers. [NOTE: a few users complained the device did not function in that manner by design. I can assure you it has no issues reading and writing to two SD cards mounted in the unit.]

    SETUP: 2014.5 Macbook Pro running OSX 10.15.3 with Uni USB-C 3.0 mated to Mac USB port directly (no USB hub).

    MEDIA:

    -Samsung SD 500GB card connected directly into the micro SD slot (no adapter)
    -Sandisk 400GB card connected via card adapter into larger SD slot. (w adapter)

    ANOMALY: THERMAL ISSUES

    Upon insertion, Spotlight indexing alone caused the Samsung SD card to get red hot to the touch thus warranting an immediate shutdown and removal of the device.

    -Spotlight was disabled and the Samsung card was reinserted without thermal issues.
    -Sandisk SD card inserted. No issues.

    Data transfer was then started with a few small files at a time without issue. 2.26GB of docx files were then transferred without issue. When moving large amounts of data however, the card got hot. So did the entire USB card reader. UNI device warm to the touch. Card temp nominal temp. No rise detected.

    The transfer results were successful. This device does work regarding Form, Fit and Function. However, the heat issues are something one should be weary of.

    Reason being, as a comparison, I ran the same Samsung SD card in the old Sandisk ImageMate All-In-One model and allowed Spotlight to index the entire 500GB card. The card was luke warm while the reader body was cold. Now, as to whether or not the circuit board inside was getting warm or not, I cannot attest to that but, I can attest to the fact the temperate of the SD card itself was luke warm. And that is really what matters. A scorching hot memory card warrants attention. I can copy the entire contents and move it over in one operation without the cards melting down on the old workhorse (Sandisk ImageMate All-In-One) .

    For smaller data transfers or, perhaps other applications on other computers this UNI USB-C reader may operate okay. I cannot say without testing it myself in a reliability lab for months on end. The OEM making these should have done a DOE and all the Environmental and Reliability Testing to ensure thermal runaway was not an issue. It is an issue that warrants attention.

    SUMMARY: Great form factor. No fitment issues. (Note: I hope users are aware of the direction the cards go in. It sounds like some are jamming the cards in in the incorrect orientation. I had no fitment issues on the 2021 model. Transfer speeds were quick. Hundreds of GBs of data were moved without corruption.

    The only anomaly or issue rather of concern is the thermal rise at the SD card level. If they are using the body of the device as a heat sink to wick heat away from the components inside, I get that aspect. It is a very small form factor but, the question is where is the heat originating: The card or the electronics inside? I would not take a chance on a scorching hot memory card being reliable and holding out for any length of time - especially on repeated thermal shocks like what this device subjects cards to.

    This thing is a lifesaver it transfers photos to your computer instantly great if you have a pc to transfer photos too I was using my cameras built in app to transfers but this thing is awesome, also very nice to just keep in a camera bag due to the small size of it
