I am highly disappointed with this memory card overall. I bought it for 450rs and it was a waste. Out of 16gb I got only 11.2gb to use which is very very less. It's transferring speed is extremely slow, approximately 2 to 3mbps and because of this I have to wait for a really long time to transfer files on my laptop. Also the reading speed is very slow, I connect the memory card and it takes some 20 to 30 seconds to show up the files.
One big problem with this memory card is that, many a times I connect it and it doesn't get detected on my android. And sometimes it gets connected but shows that my memory card has no files in it. I've also formatted it twice but nothing changed.
