Customer Rating:
Summary: ineffective product
Comment: I bought the product to use in my digital camera and it did not work and could not format it in the camera; though, the old memory card reformatted just fine.

Summary: Go Big or Go Home
Comment: Works fine, but for not much more you can buy an 8GB card that's much faster.
This one was pretty slow, and I ended up buying a new 8GB card that's 3x's as fast for not much more money than I originally spent. Go for a larger, faster card, you'll be glad you did.

Comment: You can't go wrong with a San Disk memory card for the prize. I would not recommend buying an off brand name.

Summary: Works for Kindle
Comment: Memory card is a commodity and there is no big difference in itself other than specified performance spec. This card has been performing fine so far and I use this for my Kindle. I put MP3 files to listen to music while reading books or browsing the internet.
This one is SDHC format and if you think about using this for your DSC, remember to check its compatibility. Old digital cameras cannot read/write SDHC card. It might be better to buy a new DSC first though.
