Couldn't be happier with this product!

I recently purchased the uni SD Card Reader (USB‑C to Micro SD, USB 3.0 Dual Slots) and I couldn’t be happier with how well it performs. The build quality feels solid and reliable, and the compact design makes it super convenient to carry around.The high‑speed transfer rates are exactly as advertised—moving large photo and video files was quick and hassle‑free. I also love that it has dual card slots, making it easy to switch between SD and Micro SD cards without needing extra adapters.Setup was effortless: I just plugged it into my device and it worked instantly with no drivers or complicated steps. Whether you're transferring media, backing up files, or editing on the go, this little card reader is fast, dependable, and incredibly handy.Overall, a great product with excellent performance. Highly recommend!Ver más

THERMAL ISSUES ARE A CONCERN

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.Ver más

Fast, Simple, and Works Across All My Devices

This SD card reader does exactly what it’s supposed to do, and it does it reliably.I’ve been using it with a MacBook and an Android phone, and it worked right away without installing any drivers. The USB-C connection is convenient, and the dual slots for SD and micro SD make it easy to move files between cards and devices without swapping adapters.Transfer speeds are fast and consistent, especially compared to older readers I’ve used. Photos and videos copied over quickly with no disconnects or errors. It feels well built for its size, and it’s compact enough to keep in a laptop bag or pocket.One small thing to note is that it’s very lightweight, which is great for portability, but it also means you need to be a bit gentle when plugging and unplugging it. That’s not a deal breaker, just something to be aware of.Overall, this is a reliable, no-nonsense card reader that works across multiple devices and operating systems. If you regularly use SD or micro SD cards, this is an easy recommendation. 5 stars.Ver más

I have an older camera and wanted to download photos to android phone and save to cloud. Im a klutz with technology, but it was easy. Price reasonable.

A very Fast and Reliable Card Reader

This card reader works exactly as I expected. It’s very compact, very easy to use, and transfers files quickly. I also like having both SD and microSD slots in just one device. The only small downside is that the cards fit a bit snug, but overall it’s a solid and reliable card reader.Ver más

Works great as intended, versatile USB type A or C connectors

Works as intended, love the fact that its dual purpose that can be used via USB-A or with faster USB-C connections. Used it on both and it worked fine either way. Seems to be very durable, fantastic value for the money. Have bought uni brand USB adaptors before for a MAC computer before, and they worked quite well. I definitely recommend.Ver más

Fonctionne très bien

Je n'ai testé qu'avec des cartes micro SD et la lecture se fait très bien sûr PC via USB et sur smartphone Android via USB-C.Semble de bonne qualité, pas de jeu lors de l'insertion de la carte.
