Mod chip Help Please!

[CeNM]

Hi,
Well, as I am new to PS2 I don't know much about it. I found the Neo SBOX USB chip and I have PAL PS2 . I haven't bought it yet, though. Does anyone have this chip installed ? Is this chip good enough and, does it work fine with the PAL PS2. Please, if anyone could help, me get some information about this SBOX. And, is 1 SBOX for 1 game or is 1 SBOX for all games ? If anyone could help, I would really appreciate ur help.
Thank you much :-)
Hope to get a reply soon.
