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

This universal SD card reader works great. Love that it is so versatile and compatible with laptop and phone with its USB-A and USB-C interfaces, and has slots for microSD/SD. Price is great too. Excellent value.

I've had a few products like this some of them with wires and plug in USB some of them that plug in USB with a couple different ports other than the c type this one I like because it's compact it fits right in with your SD cards and most standard SD card holders it is real easy to install use it for many different things like checking my trail cams and the location that they are at rather than switching out SD cards the size is perfect it's a great value for your money and picture quality is perfect for my needs some people out there might need something a little more specialized but I'm sure you know who you are and what you need this works good for the average person who just needs to upload some stuff or have your computer run on different chips for different reasons

I didn't expect this to be so easy to use! So much easier than using the app for our dash cam--that thing is so awkward. This reader is ideal and I'm so pleased to have it.

I had files from word doc on here, pictures and some other things I wanted to keep. Not realizing this card wasn't empty, I used it for my baby monitor. The baby monitor did it's job and saved files onto the card, the monitor told me it was empty. So naturally I assumed it was empty and didn't have to format it. When I realized my mistake, I tried to get into the card and delete the videos from the baby monitor. No such luck. This device refuses to come up on my computer and phone. I can't tap into it. So the information I saved, is virtually useless to me now. I'm going to lose it all because I can't get into the card to transfer the data. I don't know what else to do! Both pieces of information are NOT compatible with one another and it's giving me a problem trying to access it. However, the reader works PERFECTLY FINE with anything else. But this one card. I put it back into the baby monitor and it says it's working perfectly fine. So the problem is and is not the card. THe information stored on it doesn't function well with the new videos stored on it. I bought this SOLELY because it said it could read video footage from dash cams, baby monitors, and cameras. Well apparently it cannot.

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.

Nice and compact does the job perfectly, you just need to figure out which way is up for your memory card, other than that it transfers perfectly.

Been using it a lot over the last several months. Reliable, compact, works well and as advertised with both USB-A and USB-C (which is a handy feature).

LOVE this little device!! Very easy to use, no installation software, functionality is just plug and play. I bought this to use for my dashcam mini SD card and it doesn't disappoint. For something simple and inexpensive, this memory card reader is perfect for on the go. Connectivity is simple, just plug into my computer and save my videos.

Great item and value for money

رهيب عملي وحجمة مره صغير مايضايق

Perfekt!

Il prodotto ha le dimensioni di una chiavetta USB classica, il lettore di schede doppio per SD e microSD funziona bene ed è veloce. Testato sia in ambiente Mac OS che Windows, non si sono riscontrati problemi di connettività. Collegato a smartphone Huawei è stato riconosciuto e ha letto senza problemi il contenuto della scheda inserita. La comodità di avere la porta doppia con uscita USB 3.0 e USB C è molto comoda per trasferire file da telefono a MAC/PC senza ricorrere a sistemi cloud o altri sistemi. I materiali sembrano resistenti e di qualità. La finitura grigio siderale lo rende elegante. Avendolo appena ricevuto non ho avuto modo di valutare la durata e le prestazioni nel tempo, ma promette davvero bene ed in ogni caso è economico.

Shows up on my desktop right away, unlike my old reader : ) that took ages to appear. That's what I really like. Just wish the slots were on opp sides, though. There were times I needed to use both the SD and Micro SD cards at the same time ( like for transferring ) and it gets a little tricky to slot them in.
