It's outstanding. Two cards combined into a single. So for 80.00 you can compairativly say you have 16GB for 80.00
Here is something interesting I had read on another site (No Link - Browser Died before I could bookmark)
"The CR-5400 is a dual slot adapter that converts microSD/microSDHC into Memory Stick Pro duo and provides 16GB of memory.
The CR-3100 allows you to combine four SDHC memory cards, totaling 32GB storage in your PSP. Just combine 2x8GB SDHC in one of their dual adaptors slots to double that!"
(EDIT:)
I see how it works now. Just ordered the CR-5400 and two 8GB MicroSDHC cards. You take two of the CR-5400's each with 2 cards in them (4) and then you have the CR-3100 which has two ProDUO Slots and each takes a CR-5400. So it's like having 4 memory cards in total. It's really a neat design. The CR-3100 attaches to the back of the PSP (Like a plastic screen cover would on the front) and it has a small line that runs to the PSP's ProDuo Slot.
GREAT FIND Gr8npwrfl !!
