A Little Expensive, But Worth It!
The card is a bit expensive since you end up paying US$ 27 for a card with value of US$ 20, but still worth it. I ordered one and will be getting Flower for PS3 as well as Silent Hill for the original PS one. Very convenient for those of us who don't own Credit Cards. Not to mention the fact that fans can enjoy the goodies from the US PSN, which is the richest incarnation of PSN from all over the globe when it comes to content. Great buy!

200 HKD PSN Card
Worked without a hitch on my US PS3. Great for grabbing some Japanese PS1/PSN/PSP games.

Easy/Great Buy
Always wanted to purchase DLCs and PS1 classics from US PSN and living in Malaysia kinda makes it complicated, with account problems, no network card sold anywhere...having a US PSN account and the network card, now I can play Silent Hill 1 on my PS3! Up next, MGS1! :)

Easiest way to buy contents off Japanese PSN
If you ever need to buy those classic shooting games or other contents from Japanese PSN which only accepts Japanese credit card, look no further. Just get this card, key in the codes and voila, you're good to go!

5000 Yen PSN card
Highly recommended. Makes it easy to buy Japanese content off the PSN store for people who don't have Japanese credit cards.
