Pros: Was not working long enough to report any pros...

Cons: Insert in my Fire Tablet and it recognized the memory first without any issue. Then I started to copy content to it. After about 2 hours the Fire Tablet just didn't recognized the memory card any more and all installation were lost. Another Sandisk sd card to check on my tablets memory slot works just fine. Checked also with the SD card adapter in my laptops memory card slot. Nothing anymore. Disappointing. Didi not last very long.

Overall Review: I will give a replacement a try and see how it goes.
