Great micro SD card. Read/Write speeds are just as advertised.

WARNING!!!!
Please be cautious of where/who you are purchasing from, as there are counterfeits floating around. Do some research on how to spot counterfeits before ripping open the package. If the package looks good, inspect card. Look out for how it is painted and where it is made. The real card says its made in Korea, and the edges are painted white. Last final check, run the h2testw tool.

FAKE Samsung Evo.

Reviewed in the United States on July 12, 2015

I bought this off Danitra, and I have had issues with it since I put it in my new acer aspire switch tablet.
First I thought it was something to do with the tablets microSD controller, since it was writing EXTREMELY slow, and everything kept corrupting on it. Till I finally did extensive research about it and noticed that there are FAKES out there, though the packaging didn't suggest it was a fake, i.e wrong english grammer etc.

I found a forum that said to use H2testw to test the microSSD card, which I did.
and it came back with this:

The media is likely to be defective.
115.1 MByte OK (235772 sectors)
60.3 GByte DATA LOST (126527236 sectors)
Details:60.3 GByte overwritten (126527236 sectors)
0 KByte slightly changed (< 8 bit/sector, 0 sectors)
0 KByte corrupted (0 sectors)
2 KByte aliased memory (4 sectors)
First error at offset: 0x000000000731f600
Expected: 0x000000000731f600
Found: 0x000000000732f600
H2testw version 1.3
Writing speed: 10.6 MByte/s
Reading speed: 15.7 MByte/s
H2testw v1.4

which means its pretty much unusable, (same as a fake?)

64gb of pretty fast memory for my phone. Write speed of this card is fast enough for my photo needs on this Note 3. I can justify the extra cost for faster cards for my DSLR, this card is great price for phone duty.

Works right out of the box

I'm writing the review 2 months after my purchase because I live outside the U.S. and a relative brought it back home.
I bought 2 of these cards and it works right out of the box. I used them on my HP Stream 13 laptop and HP Stream 7 tablet (also bought in Amazon). So far it's still working. Will post comments in case I encounter some issues in the next couple of weeks
