Worked with Magento 22.214.171.124
At first I thought it wouldn't work. But it actually does. You just need to modify some files if you're not using a default Magento theme.
Always remember that once you install, you can't see the snippets instantly. There are a few hours or days of delay before you can see your snippets live in the search results.
Anyway, you can use the Google Structured Data Testing tool here: http://www.google.com/webmasters/tools/richsnippets to see the results immediately.
Don't forget to clear your Magento cache once this extension is installed.

There is no issue with this extension (126.96.36.199)
This extension works as advertised. I tested in a development server to determine if these uninstall and crashing issues exist. They don't. So let's start there:
Disable your Compilation before installing and then run the Compile feature (don't just re enable it) This is why your page "crashes". This is standard practice for ALL extension installations.
You can add the code required for Rich Snippets manually into your theme, there are plenty of guides out there to do this. But this takes time, effort and maybe some extra time to work out the bugs. This extension will save you a day easily.
(I really rate it 4 stars but this doesn't deserve all the 1 star ratings so bumped to 5)

The structured data task has been on my "to-do" list for ages, but had been a bit of a daunting job up until now. This extension is brilliant and works like a treat, does exactly what it says it will do. Tested as working in the Google structured data tool.
I had a slight issue. I disabled cache and compiler before I installed. When I tried to re-enable compiler it broke the site, front end and back end. I fixed this by disabling compiler by commenting out line 29 in /includes/config.php This got the site back up and running. I then reinstalled compiler in Magento Connect.
I wait with anticipation to see the the results in Google. Many thanks to the developer.

Utterly and completely useless
It simply doesn't work. At all. Giant waste of time. Crashed the site and the server.

I almost got scared by other comments but I gave a try.
This extension is a must and works perfectly!
If you have trouble, check your servers infos and if compilation is enabled (should be disabled).
