Summary: Several months ago, I wrote a review stating that I rated this was an impeccable product. That sentiment has since changed. I indeed did purchase two of these. I have found that they are prone to failure and are significantly flawed devices.
Pros: High Capacity Fast real-world performance speeds Comes pre-formatted out the box in exFAT format which avoids the file-size limitation of FAT32 and offers maximum compatibility with most operating systems and devices.
Cons: Poor manufacturing process Prone to file system corruption requiring reformat Prone to complete device failure.
Summary: Not sure if this is a phone/OS thing or a thing w/ this card, to be honest.
Pros: Excellent price, tons of space
Cons: WP8 supposedly supports this SD format, but when I tried to take lots of pictures in succession or take a 1min+ 1080p video, the camera would lock up and the card would wind up corrupted. I'd have to put it in a Windows PC, "repair" the disk, then put it back in the phone. I tried a (very) old 2g...
Summary: I got it on sale, and at the sale price, it was a pretty good deal. Full price, it wouldn't be that great a value. Make sure your device supports SDXC cards and, preferably, ExFAT. Card comes in ExFAT format, but you can reformat it as FAT32 if your device doesn't support ExFAT.
Pros: 64GB, "ultra" class card, exceeds class 10 speeds I use this for action shooting with my Nikon D5100, and the high speed of the card keeps the camera ready for continuous-mode shots. High capacity means I never have to worry about running out of space, and I can pop it in the camcorder for extend...
Cons: Adapter did not work, either with this card or any others I happened to have. The actual micro SD card physically seems to be a little bigger than standard or maybe just has a rough edge, and it's hard to get it in and out of most card slots. It jammed in my card reader and I had to pry it out. S...
Summary: not sure of reliability as yet but no problems on that for the first week. In my transfer test I transferred a 300mb file on to the card. It varied in speeds from 4.5mb to 6.3mb but no better then that.
Pros: it works
Cons: slow compared to advertised speed. I have class 4's faster than this. Because of the advancement in tech this product is a bad rep for the newer XC's coming to say they are not a fast. This also does not work in most hardware because of the newer tech it is.
Excerpt: Needed a card that was fast and had plenty of space for raw photos. I've only used it a couple times for time-lapse and it keeps up with my 60D doing long exposures. However, when I import into LR4, only imports a few photos from the card and I get a message that some of the photos could not be...
Excerpt: I purchased this sd card with the kodak pixpro az651 camera.
It was reccomended in the caterlouge as compatable
but when I placed it in the camera I kept getting a error message. turns out that it is not compatable with this perticular camera.
Summary: There was a glitch in the system when I was trying to order this item and the first time I put the order through it did not work and it asked me to re-do it. I re did the order and thought all was well. However, when the parcel arrived I got two.
defective but sandisk replaced it free. all is ok now

Summary: This card gave me so many problems. My phone always had issues with rebooting from freezing. It corrupted music and also made the mp3s sound horrible. I'm glad to say they swapped it for a new one. This one is great. I have no issues now.
Summary: This SDCard stopped letting me write on it after 1 year of use. Reading files such as audio, video pdfs functioned properly, but it wont allow me to write to it or delete off of it. I really love this before it failed on me.
Summary: I just had this card die in my Samsung Galaxy Note 2. Can't write to it anymore as any changes get removed as soon as i reboot or unmount the card. Videos copied to it do not play, some of my MP3's on it also don't play anymore.
