Great card but problems with my Android?

Summary: This card reads fine in my Android, shows up as 31.68GB or something like that, takes pictures, records video. However, every once and a while, photos stop loading, I can't take pictures. The card almost acts like it's corrupt, then if I unmount/remount the card or restart my phone, it's fine again. This worries me and makes me think I got a bad card and that one day remounting it won't help and I will lose everything.
Summary: This is a great card for holding a lot of photos without having to switch cards all the time. But I've encountered an issue with downloading it onto the computer, not with one 16GB card, but with two. So, I know it's the 16GB capacity cards themselves. It's a tedious process, but it works. I would suggest getting several 8GB cards instead. But this will do the trick if you don't want to carry a lot of cards around.
Summary: I configured this card as primary on my Nikon D7000 using an older SanDisk Class 10 16GB card as a mirror backup. Over the first week of use, my camera rejected this card at least 3 times marking it as unusable and automatically switching to the backup. I am returning this card for replacement.
Not sure its measurably better than slower class cards
25 July 2011
Summary: I purchased this card for use in my Nikon D7000 camera, which is one of the few devices that can utilize the faster speed of a Class UHS-1 card. As a casual photogragher however, I do not see faster read/write speeds than using the slower and cheaper Class 4 card in my second memory slot. I also do not see a speed improvement with this UHS-1 card when downloading the JPEGs to my PC.
Summary: While the card is very fast when used with my Canon Rebel T2i, I have had an issue with getting my Macbook Pro (Early 2011) to read this card. This computer supports SDHC cards up to 32GB and SDXC cards up to 2TB with a direct PCIe connection. I contacted the SanDisk Extreme support dept. in February and was told that a fix was on the way for this issue and in the mean time to use the usb port on my camera to transfer my photos.
Summary: Those of you who are thinking of upgrading to an Extreme Pro card over the Extreme III. Think again. Sandisk says it is an upgrade in write speed from 30Mb/S to 45 Mb/s. It may be the case but when I tested both of these in my new Nikon D7000 it didn't make a difference. I was able to crank out 9-10 shots at 6 frames per second shooting RAW files with my 8GB Extreme III now with the 8GB Extreme Pro I can do 10-11 shots if that.
Summary: This is only about 10% faster (i.e. 2.7 seconds between raw photos as opposed to 3.0 seconds between photos) than a ridata lightning class 10 card (which is significantly cheaper). So for this camera I don't think it's worth the premium. I understand for some cameras the speed increase is significant, just saying the d3000 is not one of these.
Summary: Bought this for my Samsung Galaxy S4 external slot, it works and I don't do anything fancy with the card and the data, but running the speed tests that Android has on Google Play the SD Card isn't as fast as SanDisk is publishing.
