Excerpt: 4GB is really small by today's standards but I got it for use with the RaspberryPi and making an image takes the capacity of the card it so this size works out perfectly. Also, it came with a SD adapter which wasn't listed, bonus!
Summary: I was hesitant about getting this memory card for my camera because other sd cards that had the micro sd did not work. But the price was great so I decided to try it and it works! Now I can take photos without worrying about running out of space any time soon.
