Pros: Easy to connect
Works as described

Cons: Image is slightly overscanned (at least with some combinations of Mac Mini and TV)

This does exactly what it says: adds audio to the HDMI output from an older Mac Mini (which doesn't send audio out via a regular Mini DisplayPort-to-HDMI adapter) so the audio plays through a TV. So that's great.

What's a little irritating is that the image on the TV is now slightly overscanned - you lose a very small amount of the image at all sides.. Using the previous (non-audio) HDMI connection, the image was perfectly sized to the screen. Somehow this device is interfering with my LG TV's ability to correctly negotiate screen size with the Mac.

The Displays control panel on the Mac now has an "Overscan" check-box, which didn't appear before. Unchecking the box shrinks the image so you can see the whole thing, but then it displays inside a wide black border.

So the options are either a slightly-too-big screen image, or a much-too-small screen image. The slightly-too-big one is not terrible, so i'm going with that, because the addition of the audio feed is a huge improvement.

So not a huge complaint, just a quibble. But clearly some combinations of MacMini and TV will not set the screen size exactly right.

Pros: No effort to install. Plug in the cables and go.

Cons: The red light is kind of annoying.

I picked this up so I could integrate my late 2009 Mac Mini into my home theater via HDMI. It does exactly what it claims to, I am able to view content at 1080p with dts and AC3 without issue.

Pros: moonrise seems to try hard to resolve my issues, give them a 10 for customer service

Cons: just got a replacement unit form monoprice, it does the same thing as the first unit i had - unit goes on an off intermittently.

not so good, can't rely on this product...

Pros: Everything needed for non HDMI equipped macbooks to display on TV monitors..

Cons: Lacks informative instructions and data.

Note for existing and future purchasers: Before going into a panic and blowing your top after connecting to your Mac and only getting only audio, be sure to check your mac's display settings for the proper output. Mac default setting may be at 1080p, at least mine was. The monitor I was connecting to only displays 1080i ! If Mac output is incorrectly set..you get audio only ! So before you give up and ship it back thinking it doesn't work check your display outputs...just a heads up..

Pros: - Reasonable cost (replacing an another version from a different brand which was 3x price)
- Allows my old Mac mini to act as a HTPC

I bought this to replace a dead Kanex adapter, and so far so good! Video and sound seems to work (minor under-scan on video, but still trying to adjust settings), and the cost was 1/3 of the Kanex. I like that it also came with the TOSlink cable.
