Pros: Great read/write speeds well beyond the advertised specs. I am getting sustained Reads close to 80MB/s and Write times at 17MB/s. It is much faster than my other Class 10/UH1 rated 16GB cards. Works great in my DLSR and I plan on getting some more when they go on sale.
Cons: I wish I knew these were this good, or I would have gotten the 32GB card.
Pros: Using card on my Canon T2i. Works flawlessly. Records HD Video without any problems. Camera recognized card immediately and formatted it to exFAT partition. Average read and write speeds were consistent. 15MB/s average.
Pros: I purchased this card for my Samsung Galaxy S3 to replace a smaller Kingston Class 4 4GB card. File transfers from my PC are noticeably faster and files on the drive encrypt quicker than before. This was $12.99 as part of a code and is worth the price.
