PNY 16GB Performance Class 4 SD Card (2-Pack)

#1 - errors! #2 - Because they are made rough on the tab side and have to be forced into an SD slot, the only brand that ever hung up in a camera and broke (twice over the years). Cost me $25 to have a camera shop salvage the photos on it. Now with a new camera and bought new SD cards, I had just forgotten the bad experiences until I experienced the same issue - with the size of it?? too wide?? Numerous error messages the first day, camera can't recognize. Card reader can't recognize. Requires removing and inserting again with a little more force before it will work. I'm worried about doing some damage inside as hard as they are to insert/remove. Back to SanDisk for me. update 8/2 - after taking dozens of photographs for 2 days and sorting them into folders, after the last batch I inserted the card in the PC to review, and it had somehow changed to READ ONLY. Couldn't do anything with the new images or the dozens already in folders! Removed the card and said a prayer, put it back in and this time it worked right. Then I started copying the folders onto another new disk for backup (unfortunately another PNY since SanDisk hasn't arrived) and it let me drag/copy 5 folders then stopped. Wouldn't let me drag the rest of the folders anywhere, not even to Download. I had to open the rest of the folders one by one, drag the photos one by one to the new card, then set up new folders on the new card to move those photos to. Lots of wasted time from junk SD cards!
