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

Compact and Useful
This is a great little card reader that has the regular USB-A and also a USB-C connector so you’ll be able to pretty much connect it to anything. No excessive cables to deal with so it’s clutter free when inserting into the USB port. Super easy to install. It’s super compact so perfect for on the go and even at home it’s a great value if your PC or device needs a card reader.

Nice
I have bought several of these and used them. They work quite well and I haven’t had no issues. They are very easy to use and I think better than having to insert or take out an SD card from a device like your laptop or other device you’re using. It’s quick and easy. Very handy to have around as it will take a regular sized SD card or a mini SD card. It also has two methods to connect with at either end like a USB-C and a USB-A.

Works as intended!
This USB device is really neat, considering it has three forms of connections, the SD card to type-c to USB. Its really fast at transferring large files, and feels like it’s built to last. It’s truly a great pickup for a low price tag.

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.

Resulta verdaderamente útil, me ha sacado de muchos apuros, poder transferir datos de mi cel a una USB redujo considerablemente el uso de computadoras y me ahorra mucho tiempo y dinero.A veces necesitas datos a la mano y no hay una computadora cerca para ello.Lo único que me disgustó un poco fue la falta de ergonomía en el lado de la entrada tipo C.El cuerpo del producto es muy tosco y la entrada tipo C corta, por lo que a fuerzas debo quitarle la funda protectora a mi celular.Fuera de eso un muy buen producto, la velocidad de transferencia de datos es lo que debe de ser.Tiene una estética muy chévere.Como dato curioso, necesitas el adaptador de la micro sd para integrarla al adaptador.Y este queda muy expuesto, bastante tosco a la vista a mi parecer.

Wie in der Beschreibung – Metallgehäuse – Funktioniert einwandfrei

Funziona bene
