Bought the 64GB card for my Samsung Galaxy S7 Edge. Packaged fine, arrived fine, was easy to install.It formatted without complaint. I used an app to benchmark the card, and it showed up with an average readspeed of 76.83MB/s and write of 25.6MB/s. These speeds are not as fast as claimed for the UHS-I class, whichis supposed to reach more than 100MB/s. However, it does act like a class 10 card speed, which is usually fastenough. If you do lots of videos, you might want something faster.

I bought this for use in a Raspberry Pi 3 and it quit working or became corrupted in 5 weeks. I properly formatted it for it's extended size, and reinstalled the OS's and it never worked in the Pi again. But it is still usable in my laptop, just not in the RPi 3. I don't know if I could use it in another device in the future. No wonder it was so cheap on sale Thanksgiving day.

Packaging came in without any defect. I bought this USB for my tablet. The usb is great, it’s able to save files.There may/May be a huge delay when transferring big files from computer to micro usb. It did take few hours to transfer 20GB worth of files from computer to this usb.Other than that, transferring smaller files (less than 5GB) was fast. Expect instantaneous copy of files for MB sizes.

Well worth the Money. Works perfectly (as extra storage space) with my new LG phone.

Instructions not entirely clear for inserting into phone; but works like a charm

Bought this to expand my Samsung S8+ memory. Works correctly.

It's a memory card... it stores data. It works. What else can I say? I don't use it with anything that demands blazing fast write speeds like a high-end digital camera or anything, so the speed on it works fine for my needs. Easy 5 stars.
