Pros: Great if you've got an old laptop hard drive lying around or need a new enclosure as I did. Copied my Sony Memory Stick Pro Duo 4GB from my PSP in about 10 minutes and my 512MB SD card from my camera in about half a minute. A must have for photographers who don't want to carry lots of memory cards with them.
The screen looks really nice and the build quality is good.
Uses NP-60 batteries which my old camera used so I have spare batteries I can use with it.
Can charge off of mains or USB, but note UK customers the power adapter this comes with has an Americas flat pin style plug, however it is rated for 240V so it does work with a shaving plug adapter or similar.

Cons: Drive doesn't spin up when used as a USB drive unless there is some charge in the battery or you remove the battery. Included case is poor quality wouldn't really trust the belt loop.

Other Thoughts:

Bottomline: Great if you have a drive and don't want to carry cards with you, works with my Western Digital drive with 8MB cache.

Pros: - Status screen better than expected - all important data is displayed
- Battery can also be charged via USB port
- Fast transfer rate (4Gb Sandisk Extreme IV UDMA card under 10 minutes)
- support multi FAT32 partitions
- All cables etc included (even screwdriver)
- Can be used as external hard drive with built in memory card readers

Cons: - 100-240V AC adaptor only compatible with USA power connector - Don't forget to purchase "Flat to Round Power Plug Converter - $1.21" to use in Europe (not a big deal)
- must be careful inserting CF card into slot (not so big problem).

Other Thoughts: - Included cheap protective bag is very good because it protects enclosure from scratches.
- So cheap - especially if you have spare 2,5" hard drive lying around.
- No need to pay for additional fast and expensive memory cards while away from computer (vacations, field work, etc.)
- Copies all files on memory card regardless of type - separate Folder for each memory card

Bottomline: Remarkable product for this price. Better than multiple memory cards for my camera.
