Summary: [...]They primarily will be used in a Canon Rebel T1i DSLR which specifies this class of card for maximum performance. Both cards initialized properly upon installing in camera and displayed the proper capacity. So far I have only taken a couple of test shots and experienced no issues or problems. I expect to encounter no issues with these cards from a reputable manufacture.
Pros: Easy To Use, Great Value, Large Capacity, Reliable Performance, Writes/Reads fast
Summary: While the product is wearing the Kingston name, it does not come with a hard case - limiting ability to carry around, unless you leave in your device. For me it is great, because I wanted to use a larger card in my family's Wii, so it was perfect.
