I bought exactly the same micro SDHC SanDisk Ultra 32GB about a year ago and which I'm using daily. This stuff is reliable, it has never gave me any sort of problem. My setup for this card is like a hard drive in a PC where I Read/Write a lot of large amount of data everytime like video files, photos, maps, documents and it has been working flawlessly. Not an instance I recall that it failed me and also it is fast. My tablet is my PC now and I'm using it for several hours each day. All of my data are set to be read and written into this external disk. I couldn't be more happier. I had use other brands in the past but somehow it didn't meet my expectations. The new disk I ordered will be my backup copy just in case I lost my tablet.
