  1.  Does exaclty what it it is suposed to.


    Not sure what to say... it is a microSD card. It does exactly what it should without any problems. Fits in microSD devices perfectly, can be used with SD card adapter to be used with full SD card devices without any problems. Seems durable and well built.

    Even came with a lime green phone charm dangle thingy to store the microSD card and can be attached to keyrings, mobile phones, etc. A bonus as I did not expect it to come with one and was not in the item description.

    Speedwise, it is quite fast for a class 4 card. Random reading/writing is faster than my Class 6 Sandisk Extreme III 20mb/s editions. Sequential reads and writes are sufficient for most day to day usage.

    Have not tested the water proof and magnet claims, nor would I want too.

    Overall, for the cheap price, I was pleasantly surprised with its speed. Would not hesitate to recommend.

    CrystalDiskMark v3 32bit results:

    Sequential Read : 17.724 MB/s
    Sequential Write : 7.301 MB/s

    Random Read 512KB : 17.569 MB/s
    Random Write 512KB : 1.838 MB/s

    Random Read 4KB (QD=1) : 6.905 MB/s [ 1685.9 IOPS]
    Random Write 4KB (QD=1) : 0.022 MB/s [ 5.3 IOPS]

    Random Read 4KB (QD=32) : 8.079 MB/s [ 1972.4 IOPS]
    Random Write 4KB (QD=32) : 0.021 MB/s [ 5.2 IOPS]

  2.  Not the Ultra II, Newer rebranded Ultra instead.


    You will receive the newer rebranded Ultra card instead, just like I did. I wanted the older Ultra II line, despite Sandisk claiming these as the same but just repackaged, which is not true (New Ultra line says on packaging "upto 15mb/s Transfer Speed... Write Speed Lower " The older Ultra II line says "minimum 9MB/s Sequential Write" and from various online reviews, the older Ultra II is significantly faster. I use this card along with some Sandisk Extreme III in my 450D. Normal shooting it sees no difference. In burst shooting the Ultra is a hair slower to flush out the buffer.

    Here is a crystaldiskmark test done on v3.0 x64:
    Sequential Read : 20.725 MB/s
    Sequential Write : 12.036 MB/s
    Random Read 512KB : 19.766 MB/s
    Random Write 512KB : 2.384 MB/s
    Random Read 4KB (QD=1) : 4.178 MB/s [ 1020.1 IOPS]
    Random Write 4KB (QD=1) : 0.020 MB/s [ 4.9 IOPS]
    Random Read 4KB (QD=32) : 4.243 MB/s [ 1035.9 IOPS]
    Random Write 4KB (QD=32) : 0.019 MB/s [ 4.7 IOPS]
