Query: Defective and shoddy merchandise

I bought this memory card a few months ago for less than the price of the Sony 8 MB card. I thought it was a great deal since it holds twice the memory for less money. DO NOT BE FOOLED! This product seems to be defective. What happens (at least to me and seemingly to several others) is that the card does work for a little while; then when one is trying to save a new game or overwrite an old save, it tells you that the save failed because the card was removed (when it was not removed) and now your data is corrupted and you have lost all your progress. Do not save your games on this card. You may very well lose it in the end. I very likely will not buy any more products from this company (at least those designed for video games) because, at least to me, their products are not trustworthy.
