Pros: Worked great for the first 5 weeks

Cons: Dead as a doornail after the 5 week mark, tried plugging it into multiple devices and none of them would work with it. Even the SD card formatter software doesn't recognize it.

Thank you for using Kingston flash cards,

Pros: Works is expected. Good price. Fast shipping.

Cons: n/a

Pros: Lots of space & pretty fast.

Cons: Can have low reliability.

Other Thoughts: I purchased two of these cards for my wife and I to use in our Samsung Galaxy Note 3 cell phones. The one I have tends to glitch and become unusable without formatting. It worked great for a while and then after disconnecting the phone from the PC after transferring files to the card it glitches and then says the card is "empty or unusable". I plug the card into the PC using a micro usb stick and Windows tells me that I need to format my memory card. So now I lost everything twice. And when I say everything I mean all the pictures I took with it of my newborn (the first time) to his year birthday (the second time it did this to me). My wife's isn't having any issues that I know of but she hardly ever connects it to the PC. Very frustrating.

Hello Dennie,
I'm Jewel with Kingston Technical Support. We apologize for the issue experienced with the microSDXC card. You may be able to recover your photos by using recovery software like Recuva (https://www.piriform.com/recuva/download). Running a "deep scan" can find data that was "lost" due to file corruption or formatting as long as that information has not already been written over. Since the card is repeatedly becoming corrupt there may be a problem with the card itself and it can be replaced under it's lifetime warranty. Please call us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and I or another available Technician will assist you.

Thank you for selecting Kingston as your upgrade partner.

Pros: Bought this for a Asus transformer tablet with 64GB SSD. Just put it in and it works. It works as an additional drive. Way faster than normal flash memory.

Cons: None yet. If it fails I'll contact Kingston they stand by their products.

Pros: It works for few months

Cons: Only last few months. 7 out of 10 Pictures were cut off when saving to this MicroSD Card.

Other Thoughts: A-Data is must better than this Kingston MicroSD Card.

Pros: Good Price, name, and works!

VERY FAST SHIPPING!

Cons: For some reason when I used this card through my USB converter it was showing as un-formatted even though it was formatted by the phone. Couldn't just drag drop files, had to plug phone into PC with data cable.

Other Thoughts: Overall happy with the item.
Item arrived very quick and it works!

Pros: Had this in my S4 for about six months- until it decided to die it was lovely

Cons: So once it died I could not get it to detect on anything- let alone mount the filesystem.

Other Thoughts: I swore off kingston computer memory long ago- looks like their flash memory is trash as well- stay away form this product for mobile devices.

Pros: I still can't seem to fill this with GoPro footage. Plenty of room left over.

Cons: Plenty of people have quality issues with the 64GB micro SDXC cards. Keep that in mind before you order. You may find less hassle with a couple smaller cards if you don't mind swapping them out.

Other Thoughts: PS. I haven't had any issues with this card. With my GoPro...that's another story.

Pros: I'm using this card in my Samsung Note II.
have all my pictures, music, and movies stored on it. perfect!

Cons: none
