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.

versatile and convenient
This universal SD card reader works great. Love that it is so versatile and compatible with laptop and phone with its USB-A and USB-C interfaces, and has slots for microSD/SD. Price is great too. Excellent value.

Direct to phone, skip the PC
I now have a way to go directly to my phone and skip the PC, works great! Update: I was not near a PC and my bodycam alerted me to format my memory card and shut off. The bodycam would not run because the memory card got a error. I retrieved my uni SD Card Reader, put the memory card from the body into it and connected it to my phone. My phone immediately asked to format the memory on USB, I approved it and the memory card was formatted and fixed. I placed the card back into the bodycam and things work fine again. This is an awesome little reader, highly recommend!

Perfect for Transferring Photos to My Phone
I was originally going to return this because I forgot my laptop already has an SD card slot. But after testing it on my phone, it works good and makes transferring photos easy. I’ll keep it and throw it in my camera bag so I can transfer photos to my Samsung phone while I’m out.

Great item, highly recommended. Best $10 I've spent on such a device.
This is a *great* item, and is SUPER useful for backing up phones, tablets, etc. It's like having an all-purpose/variable-sized USB fob where you can just swap out the MicroSD/HC/XC card (and it has a handy extra port for Ye Olde Fashioned memory cards as well, and while I don't tend to use those much these days, for quickly stripping off the pictures off a stack of old ones I had for an older camera, it worked great for that as well). Even better, you can use an adapter for a MicroSD card, plug that in, *and* use the MicroSD slot at the _same time_ - that, plus being USB 3.0 makes for speedy transfers, and having both USB-C + USB-A on each end makes it a breeze to transfer files between devices, or it works as a standalone USB fob of adjustable size. FTR, they show up as two separate disks. While I haven't used anything higher than 256GB cards, allegedly it'll work with up to 2TB MicroSD cards; I can't confirm that, though I'd believe it. Have a phone or tablet with 64GB storage? Use a 64GB MicroSD card; have a device with 128Gb? Use a 128Gb MicroSD card; have a device with 256GB storage? - you get the picture. No software needed, small, lightweight, and probably the best ~$10 I ever spent on a device like this.

Easy and Functional
Reads my SD card beautifully and the multipurpose nature of this product makes it a useful tool to have on standby if you expect to transfer/read data. It's good value, connects easily, and works like a charm.

Great price point! Great productbest part is it fits in with your SD cards no extra bs cables
I've had a few products like this some of them with wires and plug in USB some of them that plug in USB with a couple different ports other than the c type this one I like because it's compact it fits right in with your SD cards and most standard SD card holders it is real easy to install use it for many different things like checking my trail cams and the location that they are at rather than switching out SD cards the size is perfect it's a great value for your money and picture quality is perfect for my needs some people out there might need something a little more specialized but I'm sure you know who you are and what you need this works good for the average person who just needs to upload some stuff or have your computer run on different chips for different reasons

Premium & Affordable
I like having two slots for different SD card sizes. It fits micro SD and standard. It’s USB 3.0 so Read/Write speeds are incredible. It doesn’t get hot with heavy use and the quality of the product feels premium. The stick feels like your holding and expensive product, but is actually a decent price.

Il prodotto ha le dimensioni di una chiavetta USB classica, il lettore di schede doppio per SD e microSD funziona bene ed è veloce. Testato sia in ambiente Mac OS che Windows, non si sono riscontrati problemi di connettività. Collegato a smartphone Huawei è stato riconosciuto e ha letto senza problemi il contenuto della scheda inserita. La comodità di avere la porta doppia con uscita USB 3.0 e USB C è molto comoda per trasferire file da telefono a MAC/PC senza ricorrere a sistemi cloud o altri sistemi. I materiali sembrano resistenti e di qualità. La finitura grigio siderale lo rende elegante. Avendolo appena ricevuto non ho avuto modo di valutare la durata e le prestazioni nel tempo, ma promette davvero bene ed in ogni caso è economico.

Shows up on my desktop right away, unlike my old reader : ) that took ages to appear. That's what I really like. Just wish the slots were on opp sides, though. There were times I needed to use both the SD and Micro SD cards at the same time ( like for transferring ) and it gets a little tricky to slot them in.
