"Fast, reliable, compatible, buy it direct from Amazon or Memory Mogul to avoid counterfeits"

Liked the first one I purchased so much, I bought a second one. Very, very fast read and write speeds at a good price, plus SanDisk has the best software and device compatibility. Forget thumb drives - this is your most flexible, durable option. Use direct in your tablet or smart phone and/or buy a decent usb card reader you can load this in and, voila, instant super-speedy, upgradeable thumb drive. Works great in my tablet and in my newer card reader - and still kicks the butt of every thumb drive I know of even when used with my old plastic USB 2.0 card reader held together with scotch tape, lol. Have purchased several microSD cards since they first came out, from 2GB to 32GB, and all still work fine - I cannot say the same re the thumb drives I purchased during that same time period.One point - beware of counterfeits. Samsung is the number one brand so, unfortunately, they get counterfeited a LOT. So check reviews and only buy from a reliable seller. I suggest buying direct from Amazon (or Memory Mogul) - I have purchased from both with no issues.

"Failed after 3 months on Galaxy S3"

Bought this for Galaxy S3, worked like a charm for 3 months & then I started getting error messages on phone stating the card has been taken out or that it is not there, went on like this for a week or so & then one day gone. Initially I thought it was problem with phone. Popped in a 2Gb card from BB & it worked. Popped this one into the BB & same, no detection. After spending so much on an SD card its disappointing to see it go bust outside of return period.
