Pros: Allows read/write of Panasonic P2 cards - thus eliminating need for $$$$ proprietary card reader.

Cons: Driver was difficult to install. No info on vendor site. Once you load P2 drivers, then insert P2 card with adaptor, tell windows to search location on driver install (windows) C:\Program Files\Panasonic P2\Drivers\Card Then it installs and sees everything.

Pros: Nice options - adaptors plus thumbdrive. The thumbdrive is very small, but it makes an excellent keychain. Currently using the chip in my Samsung u740 phone. No problems there, speed seems fine.

Cons: None so far.
