Works great. Do your homework before you buy!

First step as always... DO YOUR HOMEWORK!
I own a brand new 27" iMac desktop that replaced an 8 year old Dell Desktop with Dell flat panel monitor. The Dell monitor still works fine, so I thought I would run dual screens. The Dell monitor is VGA and S-Video capable through VGA and DVI outputs on the monitor. However according to wikipedia: http://en.wikipedia.org/wiki/Digital_Visual_Interface
there exist at least five types of DVI. The differences are subtle for each type. This is combined with Apple moving to the proprietary "Mini Display Port" from the old "Mini DVI" port for external output in its laptops and desktops recently. Sadly when Apple markets these adapters they don't specify on the packaging whether its DVI-D dual or single link, DVI-I dual or single link, or DVI-A. You need to study the product pictures on Apple's website before you buy the one you need.
My 17" flat panel Dell monitor had a DVI-D single link connection and the reviewed product is compatible with both DVI-D single and dual link connections but NOT DVI-I single or dual or DVI-A.
Armed with this information I checked bestbuy.com to verify which location near me had this part in stock, and I was rewarded after purchase with a no hassle dual screen setup. The sales associate knew what I was talking about too which I personally found comforting and impressive.
Check to see:
1. Does your Apple device have Mini DVI or a Mini Display Port port
2. Does the device you wish to connect have DVI-I single link, DVI-I dual link, DVI-D single link, DVI-D double link, or DVI-A.
3. Search "DVI Connector Types" at wikipedia to be sure which one you have. Cross-reference this with the pictures of the various Apple adapters sold online.
THIS PRODUCT IS ONLY COMPATIBLE WITH DVI-D SINGLE LINK AND DVI-D DUAL LINK (unless you provide yet another adapter) Hope this helps! Thank you Best Buy.
What's great about it: Exactly what I needed. Available at a store without "Apple" in the name!
What's not so great: Heavy adapter may possibly put stress on the Mini Display Port connection over time
