Summary: I bought 2 of these for my cell phone in July 2013. I thought Kingston was a good brand but the first one died withing 2 months and then I put in the second one and it also died within a month. The warranty is a joke because Kingston doesn't even respond to a warranty question.
Summary: The card was bought for my phone and for the adapter which makes it easy to transfer files to my computer without having to install all the bloatware that comes with installing the phone software.
Summary: Got this microSD with USB microSD reader to use as a very small usb key, works wonder. Using CrystalDiskMark, 5 pass, 1000 MB, Reading speed is 17.29 MB/s while Writing was 10.31 MB/s. Which fits right in the Class 10.
Summary: As compared with other cards, this is as dependable as the others. K does make a quality product. I used this card in my tablet as backup. I have no problems with my pc or tablet recognizing the card. The price is a little better when on sale than others. Prices will go down as the gigs increase.
Summary: IMPORTANT: I have read reviews of this card on MANY sites and seen ONLY ONE report of it writing at or greater than 10 Mbytes/s. So if you buy it expecting that then I think you will be disappointed.
Pros: 8GB, Class 10(sorta, see below), not terribly expensive
Cons: Not QUITE Class 10. More like Class 8. Except there isn't a Class 8.
