Summary: Simple, easy and it works as claimed. Not the smallest, but small enough, and you get both SD and CF in one device. I no longer have to use my camera to download (potentially wearing out my camera's reader/writer), so I can be charging it's battery while downloading. Also makes it easy to attach to multiple computers (I sometimes use space on my wife's Thinkpad laptop--I have a Macbook Pro--as additionally backup). Great little reader.
Summary: Small and compact and handles both CF and SD cards. Will definitely save some space in my computer bag. The only real con I have at this time is that it requires the use of a cord which could get lost or misplaced. This would be perfect if it had either a built-in USB connector or some type of built-in cord.
Summary: I purchased this UDMA card reader despite some of the reviews here which allege that the reader will corrupt a Sandisk 32gb Extreme card, which is one of the cards I use with this unit. I have not found the Lexar card reader corrupts the card when formatting. I clocked both the Lexar CF card reader against my Dell built in CF card reader using a full 32gb Sandisk Extreme CF card rated at 60mb per second transfer rate.
Summary: this was exactly what i was looking for, an alternative to plugging the camera into the computer to download my photos. it doesn't need any extra software or do any processing of your photos, it just acts like a hard drive and puts your cards on your desktop so you can copy them where you want to. can't believe i didn't have one before!!
Summary: I replaced an older, slower reader with this one. It is fast. It would transfer a whole 32 GB card in 20 minutes (using a SanDisk 60MB/s card) if it could ever finish a transfer without hanging. After it hangs, it looks like the card has nothing on it, which gave me quite a turn, but upon loading in in another reader, a found all my files intact. Still, I can't recommend it.
