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 really like this device...I can change my SD card and when I like without having to remember what's on it. I have several SD cards that I have music on for my everyday use and trips. Great product..great quality and portability. I will be getting others as the ease of use and functionality is exceptional.

So excited this worked! I was worried it wasn't going to. Just make sure you're using a USB 3.0 port (usually will be blue on the inside). A little concerning, and I will update my review if it causes any issues, but the reader got quite warm during an only 13.4GB upload to my computer.Edit:After performing a much larger upload of 134GB, the performance did degrade as the card reader warmed up. However, it would return to ~170Mb/s after cooling down a bit.

I use this adapter with my dji drone so i can view the 4k videos without loading them on my phone. It does an excellent job of play back, the only issue i have with using it is the temperature it gets after playing 4k video for a few minutes. It gets hot to the touch, not hot enough to burn you but hot enough for a audible wow. Cannot say if it would do it with any other type of usage, as I only use it for my dji video.

Excellent little device. Very stable performance and works exactly as expected. Totally worth the money — no regrets buying it!

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.

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 >>>>>>>>>>>>>>>>

It doesn't have the added feature of push in to remove the TF card. It is hard to pick the card out of adapter slot without this added on feature. I would recommend looking at Micro center, but I don't know if the packaging tells you about a feature like this.
