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

I’m thoroughly impressed with the uni SD Card Reader! The build quality is fantastic—it feels sturdy and well-made, with a compact, minimalist design that’s perfect for tossing in a laptop bag or pocket. The USB-C connection is reliable and secure, and the product clearly stands up to regular use.It couldn’t be easier to use. Just plug it in, pop in your SD card, and you’re ready to go—no drivers or complicated setup required. Transfers are fast and seamless, which is a huge time-saver when I’m backing up large photo or video files.What I appreciate most is its practicality. It works flawlessly with my laptop and my phone, adding instant flexibility for transferring files between devices. The high-speed transfer rate makes it ideal for photographers, content creators, or anyone who needs reliable, on-the-go access to SD card data.

Does what it should - no issues.A decade ago many laptops and some monitors had SD card readers built in, but that has become a rarity. A gadget like this solves the problem of reading data to/from such cards.I like that this one has both USB-A and USB-C and that it supports micro-SD cards without an adapter sleeve.

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.

This little card reader is super convenient—I love that I can attach it to my keys or pouches and never have to dig for it. Works great and does exactly what it should. My only gripe? The USB cover. I wish it were attached or dangled from the main body so I don’t lose that tiny plastic piece. Not a dealbreaker, just a small design tweak that would make a good product even better.

I use this product almost daily and have for the last 8 months, it has held up well and worked good with my mac to tranfer my SD card photos to lightroom, photoshop and my computer in general. Reliable and never had any issues with it. Theres even a spot for a micro SD card which I have used a few times, Great price and highly recommend

Works great for looking at sd card from my deer cameras on my Motorola edge phone.

Great transfer speeds, great build quality, and had no issues with computer recognition and worked well with my iPhone 15 pro max
