The map is extremely fast and reliable and does in my phone (S3) and my Tablet GalaxyTab2 very neat. I originally bought the card for a Raspberry Pi B + and because it runs not tidy. I do not like pushing on the card that though, because the culprit can make poorly fixed. But the warning to all - this card type and Raspberry Pi not match. A Sandisk Ultra and Extreme Pro without doing any case there their service.
