I use 2 pcs. This microSDHC cards as data carriers for a tablet. Be transported and, if so again mainly photos and MP3 files. When playing on the tablet, it can sometimes be at the presentation of large (7-10 MB) Photos of moving to the next image arrive in slideshow mode to a slight bucking, but that does not really bother me. The cards do what they should. Underwhelming quickly, but they do it reliably. At the price 4 stars attached.
