uni SD Card Reader, High-Speed USB C to Micro SD Card Adapter USB 3.0 Dual Slots, Memory Card Reader for SD/Micro SD/SDHC/SDXC/MMC, Compatible with MacBook Pro/Air, Chromebook, Android Galaxy

Works perfectly, bought this to transfer 3D prints from my PC to my Ender 3 pro. have had no issues with card readability. Feels well-made and no loose connection when plugging in the card to plugging the device into my computer. No installation is a plug and play.

I got this to review dash cam footage in my car with my cellphone (s24 ultra). I can pop out the micro sd card from the dash cam (Rexing M2 Smart BSD ADAS Dual Mirror Dash Cam 1080p (Front+Rear) with GPS ), pop it into the reader and plug it into my phone. From there I can open the folders, transfer the files to my phone wherever I choose and it takes no time at all. If I just want to review the footage I can as well. It suits all my needs and is small/portable.

This gadget is much smaller than I expected which is excellent. Easy to carry, either in a bag or my pocket. Supports both standard and micro memory cards and functions as expected.

This is a small little useful tool. Securely plugs into a USB or USB-C socket and works nicely to transfer data from a device to SD and TF. The only thing I wish was designed differently were the caps. Although they fit snugly right now, I fear they will eventually become loose and fall off. Also, I have a tendency to remove a cap, use the device, and then forget to recap the end before walking away to another location. I just know I'll lose the caps. I just wish they would just fold away on some sort of hinge rather than just having to be removed completely. Otherwise, this is a slick, small, and very handy little tool if you need to "sneakernet" your files around! I like it.

This SD card reader has a solid build and works exactly as needed. I love that it has dual slots for both standard SD and microSD cards, making it super convenient. The USB-C connection is fast and reliable, and it worked perfectly with my PC—just plug and play with no setup required. Highly recommend!

This is a handy little gadget! It is easy to use, once plugged into to the laptop, the options are straight forward. Can be a card reader, or gum drive reader. Well worth the money!

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 ISSUESUpon 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.

Works perfectly. Way better than the last one I had. Pops up quickly with whatever micro SD card I put in. Let me format, and partition the cards perfectly. 👍 Love that it has both usb types. 👌👍❤️🙏
