Pros: is is easy to use and a very heap solution to high amounts of memory cheap for the psp. works with one or 2 cards.

Cons: the design feels quite weak, but thats to be expected because of its slimness and price. it doesnt matter once the sdhc/sd cards are inputted.

Other Thoughts: if you are having any problem just mae sure to put the cards in and then format it in the psp. if you formatted with two card then swap the two cards positions it will not work properly, obvious but keep that in mind

Bottomline: very usfull, i use it all the time, when combined with the cheap class 4, 8Gb micro SDHC cards offered on dealExtreme then it is a very cheap and fast solution to 16GB on the psp, or if you have more money than me you could get 2x 16GB SDHC cards and have 32GB on your psp. ahahah A must for CFW users

Pros: It's just perfect for a PSP system (even for Phat, which is supposed to be only accepting memory cards < 4GB), I use it with only 1 16GB microSD (I might expand that with another one, later on), and it's just working perfectly. It's fast, solid, and not as fragile as I read on most sites.

Cons: It doesn't "click" correctly in my PSP, so it's harder to get it out (you'll get used to it).

Other Thoughts: It's a must have for every pandora'd PSP, and also for some phones supporting these cards. It can take your PSP up to 32 GB (and possibly larger whenever 64GB microSD arrives in stores)

Bottomline: It's a must have, especially when you have a "cracked" PSP. Much better than most cards I've seen, and it takes 2 microSDs (!)

Pros: - a very efficient and inexpensive storage solution for your PSP !
- using 2 micro SD you can have as much as 32 GB of storage without having to pay for expensive Memory Sticks
- the way this hardware combines two micro SD is magnificent ! your PSP detects it as a real memory stick

Cons: - the build quality is not the best, it's fragile and if not handled with care and according to the user guide you could easily damage it

Other Thoughts: First I was looking for cheap memory sticks, and I found this PhotoFast CR-5400, read the user reviews and decided to give it a try.
Well, now I'm very satisfied with this product and my two micro SD placed in the same order (19040)

Bottomline: If you have a PSP don't hesitate !!! purchase one PhotoFast CR-5400 and a couple of good microSD cards.
Even if the manufacturer claims that it would work with different micro SD sizes and speed, I would recommend to purchase 2 micro SD with exact speed, brand and capacity, so that you could have a more stable performance and combo

Pros: It uses cheap and widespread MicroSD cards.
You can combine 2x MicroSD cards for fantastic capacity.
Looks pretty and good and relatively well made.
Easy to use, plug in, format, load whatever you want!

Cons: Slightly longer (0.67mm) than a genuine Sony MicroSD and makes the card slot cover on my after market DX case bulge slightly.

Other Thoughts: Really great device, a nice step up from the single MicroSD card adapters and I can keep using my 8gb cards. It's just so handy if you have a lot of data to carry around with you for your PSP, I have a couple of dozen tv shows and few films and some backup games easily fitting on my 2x 8gb MicroSD. All in all it cost me under £30 for the two cards (which I already had) and the adapter compared with £60 for a 16gb ProDuo card and then you run the gauntlet of bad fakes. Buy this and you can choose quality MicroSD cards pretty cheaply anyway without buying into Sony's elitist format.

Bottomline: This is a fantastic device and for those who want a relatively cheap and infinitely useful upgrade to their PSP.
Get it!!
