Super product at a more than fair price. Card has been detected immediately and has continued to make what they want. Because of the price I was certainly skeptical because of the costs which other dealers require at least half. But until now I was not disappointed. Also, I have no problem neither in speed nor in any other way. The apps that are installed on the SD card to run without problems, my 25 GB large music archive "feels" at ease no matter what size and Games run smoothly and without hesitation. (Why not card is Class 10) So it must not be advertised for a 64GB card for more than double to buy from the mobile phone only 58.40 GB are unfortunately available of what it cost you. The 64GB I must say that in all other cards (regardless of manufacturer) only 58 GB 59GB possibly stay over. That has something to do with the "computing means" as it also occurs in computer hard drives. (Simply put) Many there also nice fuck with .. - What so not quite right Advertising Technically 64 hear naturally better at than 58.40! but fortunately there are Wikipedia and here is also equal to the appropriate link.
