The Sandisk Ultra 32 GB micro sd card does not work with Motorola Droid phones. It lasted less than a month before it crashed, wiping out all pictures and music etc. Now it is unusable, even for other devices. As I found out - a little too late - this is a known issue for this particular size. A company like Sandisk should provide a warning on the packaging, not to use with certain phones. $25 well wasted :-(
I checked the card when received with h2twstw 1.4. It showed slightly slow write speeds compared to the class 10 spec but acceptable. Card shipped with a SanDisk adapter in a generic case but card wouldn't work with adapter-it did work with another I had. Capacity verified correct, appears to be a good SanDisk card.
If you're thinking of getting the 64gb version, think twice! I got one and it kept needing to be reformatted thus losing my data. After having it I looked around online and lots of folks have this problem with sdxc especially when used in phones.
