    • Incredible SD Card Reader!
Color: Grey
I recently purchased the Uni SD Card Reader, and it has exceeded all my expectations! The high-speed USB 3.0 interface ensures lightning-fast data transfer, making it incredibly efficient for transferring large files. The dual slots are a game-changer, allowing me to access two cards simultaneously, which saves me so much time. The build quality is top-notch, and it fits perfectly with my USB-C devices. It's compact and portable, making it easy to carry around in my bag. The read/write speeds are impressive, and I've had no issues with compatibility or performance. If you're looking for a reliable and fast SD card reader, this is the one to get. Highly recommend! ... show more

    • Great for transferring from PC to 3D printer
Color: Grey
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.

    • Quick, portable, works.
Color: Grey
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. ... show more

    • Functional and easy to use
Color: Grey
Very good read & write speeds, no issue at all with taking the cards in and out of the readers, worked out of the box. The only reason not to give 5 stars is that there’s no protection at all on the orifices the cards are supposed to go in, it’s very easy for any type of small debris to go in there, hopefully it won’t be a big problem. ... show more

    • Works well. Nicely compact.
Color: Grey
I wanted a quick SD/Micro SD card reader I could use on the macbook, and this seemed small and decent. It works well. I like that it has both USB-C and USB-A connectors in such a tiny package. That makes it pretty useful for a variety of machines I have here. If I had one minor complaint, it would be that the caps over the USB-A and USB-C connectors come off a little too easily. They'll pop off in a pocket or bag on occasion. Other than that, though, a great little reader. ... show more

    • THERMAL ISSUES ARE A CONCERN
Color: Grey
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. ... show more

    • Was a life saver, great purchase
Color: Grey
I used this as a last attempt to unwrite protect my wii’s sd card because all of my other computers with sd card slots couldn’t do anything to repair it. diskpart didn’t work, windows 10 wasn’t wanting to repair the drive, and linux was being stubborn. but finally with this I was able to plug the sd into my laptop running windows 11 and it scanned and repaired the drive!!!! Transfer speeds are super fast compared to the usb 2.0 flash drives i’m used to and the adapter feels super nice and professional with its aluminum casing and acrylic covers, i’d highly recommend this. ... show more
