"Extra storage space for Surface RT."

SanDisk Ultra 64 GB class 10 used as extra storage space for Surface RT. Everything worked as expected. Well worth the money.

"Installed Effortlessly, Fast, and Economical"

I was out of space on my Droid RAZR 16GB and still had an empty microSD slot, so I figured I'd pick this up seeing as how it is a reputable brand in flash memory. I am glad I went with the Sandisk Ultra, because there is seemingly no difference in speed between this drive and the built-in internal memory of my phone. I record a lot of videos with my phone and I've been recording straight to this card in HD with no problems at all.Installation was a breeze. I took the memory card out of the package and inserted into my phone. Then my phone brought up a menu asking if I wanted to move my music, videos, and photos to the memory card. I selected all three categories, and in minutes it had moved all of my media onto the memory card. I didn't even have to do anything else. I had read some other reviews that said they had to reformat the card or mess around with moving files by hand, but I didn't have to do any of that.I haven't tried using the included SD adapter yet, but I imagine it will work as well as any other adapter. The adapter and memory card were both shipped in a little clear plastic case, which makes it easier to carry the adapter around with you. So you have it with you when you need it.The price on this card when I bought it was a few dollars more than the generic brands. I decided to spend a few extra dollars on it since I would be really upset if I lost all my photos and videos due to a corrupt memory card. I am very satisfied with the product and I would highly recommend it to anyone looking to increase the storage capacity of their phone or anything else this would fit in.
