Purched this on sale and couldn't be happier! I bought this to use with my Samsung galaxy note 4, and it does what it is supposed to do. With this 64gb card I now longer have to worry about taking longer videos or deleting pic to free up space. No formating need, just stick it and your ready to go.

I bought this card to use in my older model 3DS which takes regular sized SD cards. Conveniently this comes with a microSD to regular size adapter. For all intents and purposes, the adapter is just a pass-through and should have no effect on the card's operation. However, for some reason my 3DS didn't pick up on it right away. After transferring my old content (keep a backup on your computer until you're absolutely sure things work), I plugged it in with the adapter and the system reported nothing. Strangely when I slide the lock switch on the card, the 3DS tells me the card is locked. About five reformats later, it worked. I've been using it for a few weeks and it seems to be working fine so far. Needless to say, I'm not gonna remove the card, not that there's much reason anymore with all the extra space I have now. The card worked 100% of the time when I plugged it into my computer, so I recommend using it for other things like phones, just not the old 3DS.

Used this sd card for the phantom 4k, good quality recording and size.

Quick read\write speed with lots of storage space. Compatible on Windows and Mac machines. Card was not available in local stores so ordered it for store pickup which took a week.

Great memory card, nice memory size and very faster...
