Pros: Worked just fine for the first month of two.
Cons: I first experienced some glitches when trying to use audio books stored on this card. Every so often, it would crash and act as though the card had been unmounted. Now at 4 months after purchase the card is no longer recognizable to my Galaxy S3. No options to reformat.
Cons: half the time the it didn't work with device it was in. When it does work it is painfully slow at most times. the best i could get out of it is abot 30mb a sec, and that was rare. Nothing but problems, already rma'd 1, identical issue with second. I won't rma again, I am switching brands.
Pros: I have never had any bad memory card product from SanDisk and this is my 7th or 8th card over the years, so go out of my way to order this brand.
Cons: Product worked for a few months and then stopped working overnight. Unable to read card, all data lost and of course this happens after 30 days return policy. Contacted SanDisk directly and of course they only warranty the product, not the content but for a small fortune you can try to get this fixed by data-recovery 3rd party service.
Cons: Wasn't able to be read and all data was lost after 36 days. Unable to format. Don't buy this. Return policy is 30 days after product arrives. Would get negative eggs for the rating if it was allowed.
