I have nothing bad to say about this product. the packaging indicated that it was new, never tampered with. it came in the mail on time and I have had no issues with the card overheating like some other reviews have mentioned. I like that fact that now I have 16GB of space and this means I can have more pictures and home movies on my phone to share. Also music for when I'm working out. Great buy and for the price I really like it. I recommend it and will be buying one more for another phone.
