[This review was collected as part of a promotion.] The amount of space alone that I was able to free up by putting a lot of my things on the card was worth it.
I would recommend this to a friend!

[This review was collected as part of a promotion.] It works!! Didn't think that I would like it at all, but I was very much surprised when I saw the durability and the reliability of the product. Its speed was average and\n Only compatible with 1 or 2 of my other devices.\n And its capacity is average, also
I would recommend this to a friend!
