The pros: tested for several months that card never asked me any problem. The flow rates of 40-45 MB / sec are the appointment and lifetime warranty is a guarantee of quality (please keep your bill, 30 year warranty in countries not recognizing lifetime limited warranty). With my camera so I can make 800 photos of 20 megapixels or 1:20 film in 1080p, that's enough, a perfect card to make a good big bursts of pictures. TOP !! Delivery Amazon at the top.
