I have a number of SanDisk memory products and they have been 100% reliable. This microSD is no exception. I purchased this memory specifically because it was the largest microSD memory currently available. i am using it for removable data storage on a Windows SurfacePro2 to free on-board SSD drive memory. Reviews of the SurfacePro2 didn't verify compatibility of the 128GB microSD but the SurfacePro2 immediately recognized it and it operates flawlessly.
