2 x 16 Gb MicroSD Mobile Ultra Class 6 (In Vacations, Buyed in Madrid Spain for my camera 3 years ago)
2 x 16 Gb Micro SD Ultra Class 10 (Buyed in Amazon, Amazon seller, 2 years ago)
and from the last year 2 x 32 Gb Micro SD Ultra Class 10 (Buyed in Amazon, Amazon seller in Dec 2014)
The Mobile Cards are working in tablets. No problem.
The Ultra 16 Gb Cards are working in 2 android phones. No Problem.
The new 32 Gb Card, one still unused, the 2nd one I used it in a MicroUSB Adapter copying data for work.
This Card failed one or two month ago when:
1.- Try to copy and unmount itsef.
2.- Format the card and 1/2 surface is bad.
3.- Delete partition, format again and the card dont respond (no partition found).
4.- Put in my phone (Galaxy S4) and said “Bad SD Card”.
5.- The card dont work anymore.
* Proved in 3 pcs, many ports usb (2 and 3), and many options (card reader, sd adapter, tablet and phone), still dont work, the card is DEATH.
PD: Amazon verified purchase
