SanDisk MobileMate USB 3.0 microSD Card Reader- SDDR-B531-GN6NN

I bought the SanDisk MobileMate USB 3.0 microSD Card Reader to use with a 256GB SanDisk High Endurance microSD card in my Tesla Model S — and it works perfectly!The Tesla instantly recognizes the reader when it's plugged into the front USB port, and both Dashcam and Sentry Mode start recording automatically. No setup hassle, no errors — just simple plug-and-play.The build quality is solid, and transfer speeds are excellent when moving video files to a computer. It’s compact enough to fit neatly in the center console without getting in the way, and it doesn’t overheat even after hours of continuous use.If you're setting up Dashcam or Sentry Mode on your Tesla and prefer using a microSD card setup (which is more reliable than USB flash drives), this reader is exactly what you need. Super reliable, fast, and affordable. Highly recommended!

I love how easy it is to use—just plug it into my laptop or desktop and insert the microSD card, and voila! My files transfer quickly without any lag, saving me precious time during busy workdays or while editing my latest photography project. The durable design ensures it withstands frequent use, making it a reliable tool in my tech arsenal.The dual-slot feature is fantastic, allowing me to use both SD and microSD cards simultaneously, which is perfect for multitasking. Plus, the compact size makes it easy to carry around in my bag, ensuring I always have it on hand for any data transfer needs.However, the reader can sometimes feel a bit flimsy, especially when inserting and removing the cards repeatedly, but it hasn’t caused any issues so far. Additionally, while it’s compatible with a wide range of devices, ensuring a proper connection might require a quick restart on some older systems.Overall, the SanDisk MobileMate USB 3.0 microSD Card Reader is a must-have for anyone dealing with microSD cards regularly. It’s fast, reliable, and incredibly convenient, making data transfers seamless and efficient. A solid 5-star rating for its speed and versatility, with a tiny star lost to its occasional flimsiness.

This is perfect for reading micro SD cards if you don't happen to have one of those adapters. Just plug it in and you can select which photos or videos you want to open and view. We used this to view photos taken with a GoPro camera, which uses a micro SD card. Easy to use, fits USB-A port on laptop or computer.

The size is a bit big, you might have trouble plugging it in next to another USB device.Amazon basic A2 micro SD card runs at 89.93 MB/s

Works as described. Doesn't require any special drivers to get it to work. Just plug it in and do your thing.

I use this item to extend PC storage during permanent use. This adapter sticks out less than an inch, which was very important for me as I use it on mini PC. 1TB SD card works perfectly with this adapter. After 5 minutes intensive data transmission it got barely warm. The data transmission speed depends mostly on the quality of SD card. With my SanDisk 1TB I got 130 MB/s or read, and 95 MB/s on write.

03/24/2023 Update -- I plugged and unplugged several times, in a different laptop -- a new model Lenovo Flex and it worked. I was able to upload 20GB of files and to retrieve them as well. Why it is working in the new model laptop? I have not idea, but I will be keeping it for the simple reason that I had planned on using for a temporary backup and would not be removing the device once installed. It may be that the thin connections, from device to device may have need to be scrubbed (old school), to help make a clean connection. That is what is seems to be - by multiple removal and insertions, maybe, the same result. Of course, this does not lead to much confidence. If it was not for a clean manufacture packaging and being a Brand name, I would have tossed it.Unbelievable -- I did not work. Came in the Manufacture, sealed packaging -- I felt good about that, but it did not work -- oh, wait, it worked for about 30 seconds then just quit. I tired a known working 128GB card with files on it and go 0 readings. I wiggled and reinserted and reinserted -- but the final conclusion was -- It does not work. I have used and still use Sandisk micro cards for years without one fault or failure, and had great confidence in this small flash drive. Very disappointed. It was a Sandisk, 128GB micro Extreme sd card that I used, and I reinserted it back into another sd card reader and it was perfect. I know, a few others said the same thing, but others said they have a good one -- really disappointed.Update: 05/23/2023 -- Nope, still a piece of junk. Not even time brings this back to life. Done with it, to the trash, to the trash >>>>>>>>>>>>>>>>

Works as expected
