Summary: bought this after my Patriot Memory 8gb card failed after about 2 years. The price sucked me in for this 16gb. 4 months in, it failed. I have no faith in Patriot Memory after these two incidents. Now looking for my receipt since it's supposed to have a "life time warranty". Windows 7 does not detect it anymore, smart phones don't detect it, Linux sees it, thankfully, and opens as a read only file system, allowing you to save your files.
Summary: I bought this card for use in my Android tablet. You can't beat it for the price. The Kingston version is nearly 3 times the price. I won't say it's the fastest card on earth but if you just want a card for Music or Video for your phone then this is the one to get.
