Pretty expensive for a memory card unless the speeds are UHS1 grade. But just letting people know that even though this is $100, it has the best value at $3.16 per GB among Vita memory cards.
For reference, the dollar per GB ratios for other Vita memory cards.
4GB: $5 per GB
8GB: $3.75 per GB
16GB: $3.75 per GB
32GB: $3.125 per GB
It's pricey, but it's better than buying a bunch of 4GB cards if you need more space.
