Works like it should., 2008-09-06 Product works great. No problem being read by card reader or photos being written to it. Fast and reliable. Great media, 2008-09-06 i will never get near the capacity that this added to my camera. great. simple. fantastic price. Lock Problem, 2008-09-06 I give this SD card a 1-star. Why? when I attempt to insert it into my laptop SD card reader, the mere act of this insertion causes the lock to switch to the engaged position, making it unreadable. The same happens on occasion in my Canon SD1000. Why would you put a locking mechanism on the device which would slide shut when inserting the card? Idiotic. It should be the other way around. Other than that, the card performed without incident. But this is a serious flaw. more space, 2008-08-30 You always need more space for pictures on your camera so this is GREAT ADDITION! No complaints, 2008-08-28 Took lots of pictures on our vacation and this did the trick. Even with high resolution digital pictures it was able to store all the 117 pictures we too and still had room to spare.
