It's not the retail packing with those fancy labels and a plastic that is hard to open. Mine just came with a hard paper envelope that was easy to open and the SD card is just in there with the card holder.
Yes, this will work fine. The Hero 2 Naked supports SDHC level 4 (and above) cards up to 32GB. Quoting from the GoPro web site: "Memory: SDHC up to 32GB capacity (Class 4 or higher recommended - card NOT included)"
Looking at the Specs for the Samsung Galaxy II Note Pad 10.1... it accepts MICROSD cards, this is a standard SD card... so it is too big for the Note Pad. You need to make sure you search for microSD cards. This is a good brand... just not the right size.
ok first the Extreme Class 10 cards are actually the same as the Extreme HD video they just changed the name. that being said there have been a few other changes as well.
SDSDRX3-032G-A21 is an Extreme HD video card class 10. this product is no longer manufactured and was replaced with SDSDX-032G-X46
SDSDX-032G-X46 is also an Extreme HD video card but this card is a UHS 1 card. UHS is part of the new SD 3.0 spec. for more info on SD 3.0 spec you can visit sdcard.org.
probably, but you might as well futureproof yourself for a better camera that can take advantage of higher write speeds. I recommend Transcend class 10 cards for the next level down. These sandisk cards are better for people using dslr's with some type of high bitrate video hack (gh1, gh2, magic lantern with canon's, etc)
