I bought this SD card because I was looking for a card with a lot of capacity, but not HC card. This is advantageous for just do not support HC older devices. In this case, I have only this card with 4GB found that fits my criteria. The quality of the card itself is not comparable to that of eg Sandisk. She's just less stable. But as for me so or so rare the card is changed it does not matter. It break in favorable cards just always the webs of the housing around the chip between the contacts from. That happened to me again and again with favorable card. SanDisk cards have not. For the particular application in my card but is well suited and does his services despite lower transfer rates.
