Pros: Have had very good results with these for some time. Best price/performance I have found so far. Seem quite fast, and no reliability issues so far. Packaging seems plenty solid too Have been my favorites
Cons: non so far Don't know about long term retention,
Summary: Based on the price and my experience with the one I already have, I would not hesitate for a second in purchasing another.
Pros: Speeds are great - inline with more expensive cards. Reliability is great - it hasn't failed in nearly a year and several removal/insert cycles. UHS works great in my camera. It reduced my camera's write time noticeably thus giving me faster re-picture times.
