Summary: Got it at the promo price (around 12 bucks), so can't really complain about a class 10 16gb micro sd card. When i played videos roughly 2 gb in size on my phone, it seemed to stutter a bit, but i'm not sure if that's my phone or the sd card.
Summary: I needed a Class 10 micro sd card for my GoPro Hero 3. This card has performed flawlessly over the last 6 months. I have shot probably 100 hours of footage and tons of pictures with no issues whatsoever. The card does what it says and I would recommend it to others. As a bonus I bought it when it was on a pretty good sale so no complaints there.
Pros: Speedy class 10 card, does what it says
Cons: None so far. 6 months of use and abuse with my GoPro Hero 3 and no hiccups yet. Would buy another or a larger capacity card
Summary: I use this with my Samsung Galaxy S2 LTE and it runs great! Speeds are as advertised, around 10 MB/s for both reading and writing. I would definitely buy another one of these. No problems so far.
Summary: It's quite quick as you'd expect of a class 10 sdcard made by a reputable company. There has been no issues with the card and has worked with every device I've tested thus far. Mostly been used in my phone, both for storage and apps, and looks like it'll carry on strong and will probably outlive the phone.
Pros: -Fast reads and writes, -No compatibility issues
