After 10 months defective - prefer other manufacturers

I have bought this card because it was faster than SanDisk cards in the same price range and I thought that Samsung is synonymous with quality.
Unfortunately this card went to only 10 months broken - she was no longer to use the phone because you could not write data to it (no downloads etc more possible), nor could delete data from it (automatically placed themselves always restores). Luckily I was able to back up all data and had me here to buy a new memory card that also works now without any problems.
Although you might think that all the great produce use the same memory as me but never a card in this way is gegagen defective (my 1st card of Samsung), I can only assume that there are differences in the processing.
Unfortunately, it is very difficult to exchange storage media after 10 months with burden of proof; In addition, you want to also do not send out data from 16GB to. This leaves only a new purchase. I can only to buy Transcend and San Disk card rates.
