UGREEN USB C Micro SD Card Reader, Type C to Micro SD Card Adapter with Zinc Alloy External, Portable SD Card Reader USB C for TF Micro SDHC SDXC, Compatible with Samsung/Mac/iPad Pro/iPhone 15 16

Works great! -Sometimes you have to push hard on the card a little bit to get it to read. -Yes, it gets very warm. -Also I wasn’t able to get it to work with my iPhone but that is probably an iPhone issue. It works great on my MacBook Air.

Speeds are great! This is a higher quality reader than my last one and is all aluminum. The micro SD card does not stick out far at all and the reader is very compact for a keychain. I used a SanDisk extreme 1TB and the image reflects its speeds.

Small form factor works great for data transfer

Card reader work very well however if I could suggest a design change it would be having the sd card go into reader further. The fist time I used it I pulled the reader out of my phone with card still in and dropped it and when it hit the floor the card cracked in half. Thankfully nothing lost. Works great I still use it but more carefully.

This micro SD reader is super handy since my tablet lacks expandable storage. It lets me use a micro SD card, which is more compact than a USB flash drive, and access its contents through the tablet's browser. When transferring large files, it does get warm, but that’s probably because metal dissipates heat better than plastic. The copy speed stayed consistent while moving 60 GB from the micro SD card to the internal storage.

I was expecting the item to be bigger than the photo showed, but it was just as small as the listing. It functioned exactly as I wanted. Nice, accurate, small

Impressed with the performance of this tiny device in tests with my new iPhone 15 Pro Max. It easily plugged in with my case still on the phone. It was quickly recognized in the Files app. An informal read speed indicated a transfer speed of about 80GB/sec to the iPhone 15 Pro's internal RAM. Saving a 2GB 4K video from the phone to a Samsung EVO Select SDXC using the adapter took less than 30 seconds. And, so far, it handles direct writes when recording in Log video format. No major heat issues as yet at normal environmental temperatures. When purchased was about $11, so it exceeds expectations at that price point and if it inevitably gets lost due to its small size its no big loss unless I leave a memory card in it. However, the keychain attachment gives you a means to keep better track of it. As others have said, the design does like the MicroSD card exposed some. Considering that the whole thing is sticking out of a port on a phone that costs more than $1,000 brand new, you'll should probably be babying the whole rig when it is attached to be safe or spend more on something more ruggedly designed if you're situation that calls for it.

Great lil device

Nice desgin, max write speed on SD is about 40MB/s vs other readers

I’ve been using the UGREEN TF Card Reader with my PC and iPhone, and it’s been a fantastic addition to my setup. The USB-C and USB 3.0 connections make it super versatile, allowing me to easily transfer files between my PC and Micro SD cards. While iPhones don’t have native USB-C, I use an adapter, and it works flawlessly with my phone as well. The transfer speeds are great—fast and reliable for moving photos, videos, and documents without any issues. It’s also compact and durable, making it easy to carry around and use on the go. For anyone needing a reliable, multi-purpose card reader that works with both a PC and iPhone 15 and on this UGREEN card reader is an excellent choice!

Se siente de buena calidad y funciona bien, la velocidad también esta muy bien por el precio es USB 3.0 ya es algo, tiene buena construcción eso si deja bastante parte de la micro sd por fuera y no es de mecanismo de "resorte" hay que insertar la micro sd hasta que tope, esta bien me gusta más y creo evita accidentes la use con una micro sd de Samsung, la conecte a mi celular y prácticamente instantáneamente la detecto (cosa que no siempre pasa con memorias USB), además tiene un símbolo que ayuda a poner la micro SD. Por el precio, tamaño y calidad es exelente. Yo pedi en color dorados y me llego plateado, pero da igual son lo mismo

Been a blast so far with file transfer, i keep it plugged into my pc at all times currently. You can just pop a micro sd card in instantly like this, just make sure to eject before removing it each time for safety!

La utilizo durante mis viajes de trabajo, me facilita muchísimo la carga y descarga de archivos. La uso con un iPhone 15 Pro Max sin temas. Lo único que debes considerar es: el material es metálico, dependiendo de cuanto la uses se va calentando, fuera de eso buen producto.
