"I think these are poorly made"
I read the instructions and followed them perfectly but it does not work for me. The PS2 either only shows an 8MB car plugged in (the size of the original) or no card at all. Seems like there are some major inconsistancies in the manufacturing process since it works for some and not others. I'd advise you not to throw anything away until you're sure it works if you buy this item. Unfortunately I did throw away the packaging before testing so I'm stuck with a new black door stop.

"Exactly What I needed"
I read the reveiws and don't understand how come people are complaining. It says clearly that you can only use this Item with a sony PS2 8mb memory card. When you use the product in the way it is advertised it doubles your SONY memory cards storage and works with EVERY game I have, including vice city and san andreas, NHL 2005, ace combat, turok, freedom fighters, mortal kombat, bust a move, WRC, grand turismo, and more.
I find it interesting that all the complaints that are in the reveiws are from people who were ignorant of the product description which clearly stated how the product works.

"plain cheating"
product packaging makes you think that it is an 8MB memory card which lets you add another 8MB in the same slot. PS2, however, does not recognize the memory until you insert an original 8MB memory into this expansion package. it is a total rip.

"This Expansion Pak Works Perfect"
Geeze, you guys and gals who are shooting down this product CLEARLY did not read the packaging or get the hint "EXPANSION". It states AND shows right on the package that this item turns an 8mb memory card into a 16mb memory card. You simply insert your 8mb card into this item and plug it into your memory slot. It is pretty much used for the bigger games like the hunting games and others that take a lot of memory to save situations. So, it is NOT faulty in and of itself (of course faulty units may well be on the market just like everything else), but it works just as it is advertised to. And if you shop here at Amazon, an 8mb memory card is not $25 but can be bought for a much more reasonabe price. And no, I don't work for Amazon or Intec. I shop here for games and books simply because they most always have the best prices.

"Need original memory card to use this...?"
A salesperson told us this would be all we need to save games, but so far it's not recognized by any of the games for our brand-new PS2. Either you need to pony up the $25 for a real memory card so that this can work WITH it, or else ours is just plain defective.

Phooey on Sony for not including SOME storage with the PS2. Phooey on Intec for not stating plainly (either here, or in the product packaging, or on their website) whether you NEED an existing memory card for this thing to work.
