I bought this adapter to use with a third computer monitor. The only available video port left on the PC is HDMI, but the monitor does not have HDMI input (Dell 1908FP). The plan was to plug this adapter into the HDMI port on the computer's video card, then connect to the monitor with ordinary DVI cable. One problem stopped this from working - the HDMI side of this adapter can't plug into the video card because the adapter is too fat. The video card HDMI port sits in between the DVI and VGA ports. A normal sized HDMI cable fits fine, but this adapter can't reach between the DVI and VGA cables. I didn't consider this possibility when I bought the thing, and of course I had to go back to the store to buy a little Male-Female HDMI extension adapter (another $20 I didn't want to spend). In the end, with the help of the extension, this adapter does a fine job allowing me to connect my third monitor to the HDMI port on my computer video card.

What's great about it: It works
What's not so great: HDMI end is much wider than size of regular cables
