The Amazon Shopper
Works great in my Samsung phone. Fast Enough to not really notice it is here.Came with an app that  shows disk usage both on card and internally, as well as Drop Box. Slightly useful.===Update: 1 year later it's become completely unreadable by any device. I was about to throw it out until I noticed that the warranty on this is pretty good. Contacted SanDisk, sent the old one back, and received a new card in a week. Bugs me that it stopped working -- it went from working to completely unfunctional in about 2 days. During that time the devices were complaining about corruption every couple of times.
