Bought the last 5 of these because the price was so shockingly low.

At $2.99 each, they cost just about the same price as two high quality DVD blanks, with the same data capacity, but handier.

I use them to transfer photos, etc. to others.

I tested them and 3 of them had strangely been formatted in different cameras. (Discovered by viewing the SD Card's name).

So, I think they were possibly pre-used in various devices. STILL a great deal, but that should be mentioned.

I reformatted them all properly with the free SD formatter program from sdcard dot org and all 5 work great.

I'll buy more if they get more at this price.
