I bought mine at 24.99 and I'm glad I did, it's crazy how low flash prices have gotten. A year ago it cost as much to buy a 16GB SD card.
As the other reviewer has noted, this appears to be a Class 4, the one I received is like the picture and denotes Class 4 on its exterior.
As always, it's good to test SD cards for fakes with a utility like h2testw, and the results prove that it is not fake and indeed a Class 4 card:
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
