Awesome product. Small and portable. Has many ports for multiple cards and reads them fast. Def worth the money. Used it for an emulator system to transfer files and id say this thing was perfect for it.

Works well and is a nice, compact, minimalist solution if you only ever need to be able to work with SD and micro-SD cards. It's also pretty convenient to have both a USB-A and USB-C option. If I could complain about one thing, it'd be that the cap for the USB-A side only has one way that it can go on because of the keyring placement... They could have easily put the keyring part lower so that this wouldn't be an issue, but, part of me feels this is a bit of an intentional design joke...giving you a 50% chance of putting the cap on correctly without looking, the same way you have a 50% chance of inserting the USB-A side into a USB port without looking. Well played R&D team, well played...

I works well for the media it is designed for, i.e., SD and micro cards. The software provided needs work on its usability. The compact design is a plus.

Works like a charm between my phone & laptop. No driver installs or anything- simply plug it in and voila! Works with a variety of cards and is very compact. It is also very sturdy and won’t break unless you try to.

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 is perfect for me. I have an old phone with an SD and I have alot of memories in it. Sadly with the newer phones you don't have a slot anymore for your SD cards only for your sim card. I purchased these so I can see my stuff I had saved in my SD card. Sure enough I plugged it in my phone and it worked perfectly with no issue. Super easy to use and I'm one very satisfied customer.

I got this to download photos from the microSD on my trail cam. It is nice and compact, and works well when I plug it into my MacBook or into my iPad. Transfer speeds were much faster than the other card reader I tried. I don't know if it got up to 56 Gbps or not, but it transferred 9.95 GB from microSD to my computer within 2 min 41 sec. The 54 Mbs device took 7 min 42 sec.
