First of all I am not rating this product as a 5 star like it the greatest item ever, I am rating this product as follows, would it have been the same product if I bought this at the retail store, was it worth the money saved to buy it online, and am I happy with the product I got in the mail. If all those are a yes for me then I will give it 5 stars. I am not just rating it 5 stars cause its the best product of its class, that is for each person to decide. I will also be updating the reviews as I see fit if I decover something in the future. Thank you for taking the time to read my review.I have has a SanDisk SD card for 2 years with my phone and it has lasted through the tough times and high heat. I bought this to add movies to my daugther's Galaxy Note 2 10.1 tablet, No changes are needed to format it just plug and play. Buy this product with any of the new Samsung tablets or Note 2 and it will just work :)
