Perfect for photographers
Very convenient and easy to use. The reader works instantly when plugged in, and the transfer speeds are fast. I like that it supports both SD and microSD cards, which makes it really versatile. Compact, reliable, and perfect for quickly moving files.

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.

Great value for the price.. super simple
Great little device.. its compact design & functionality is perfect for what I nedd.. easily transfer files & photos off the phone to multiple other devices. Instructions were easy to understand, super easy install just plug in & done, did not come with SD card or reader so had to purchase separately, but it is a great value for the cost, & great durability.

Runs toasty, but works good
Gets pretty warm under heavy use (copy large files etc.), but works good. Occasionally disconnects but Windows continues the file transfers without interruption. Lightweight and easy to use. No additional software needed.

Impressive SD Card Reader
Connectivity is easy. I really love this! However, if using this on your phone (Android), you will have to search through "My Files" so you can view or move files to there. The size of this is perfect, and I love that I can use this as a USB 3.0 or USB-C. This works great through my phone and computer, and it get's recognized quick. I have not notice any heat issues with this (I have transferred multiple Gigabytes of data on this). The data speed for transfers is quick through this too. Usually my SD card readers last me about 3 - 6 months. This SD Card reader has lasted me over 2 years, and it is still going strong. I totally recommend this!

Uni SD
I really liked it because it fulfills its promised function of being able to transfer anything we want from the phone to the SD card. Its size makes it easy to carry everywhere, and it comes with a cover that protects the phone's port. The color is exactly as pictured, and it's super easy to set up for data transfer.The quality is very good for the price, I think it's great and it seems to be made of durable material. I've had it for a while now and the durability is very good.

Fast, Reliable, and Perfect for school Work
I’ve been using the uni SD Card Reader (High-Speed USB-C to Micro SD) for college, and it’s been an absolute lifesaver. Setup couldn’t be easier—there’s no installation or drivers needed at all. I just plugged it into my laptop and it worked instantly, which is exactly what you want when you’re rushing to transfer files before class or an assignment deadline. In terms of connectivity, it’s very stable. I haven’t had any disconnects or random errors while transferring files, even with larger folders. It reads my micro SD cards quickly and efficiently, and the transfer speeds feel genuinely fast, not exaggerated. I use it mainly to move photos, videos, and design files, and it handles everything smoothly. The fit and build quality are also solid. It plugs in snugly without feeling loose, and it doesn’t wiggle around in the USB-C port. It’s compact and lightweight, so it’s easy to throw in a backpack or pencil pouch without taking up space. As for storage capacity, it works perfectly with higher-capacity micro SD cards, which is great since I deal with large files for school. It recognizes the full storage without issues and transfers data accurately every time. For the price, this is excellent value for money. It does exactly what it’s supposed to do, feels durable, and performs consistently. Overall, the functionality is straightforward and reliable—no gimmicks, just a dependable tool that gets the job done. If you’re a college student or anyone who frequently works with micro SD cards, this reader is absolutely worth buying.

Quick, easy and fast
Really quick and easy to get on my photos out of my car camera system and action cameras on the spot. Some compatible with android, it doesn't get pot. What connectivity is fast and a card reader is very reliable. Very low heat level. And the value is acceptable. Can retain storage and the protective cap keeps it safe.

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.
