Not sure why the comment section here is so bare. Bottom line up front, I like it! But, the reason I like it requires explanation. Many people don't buy these plugins for the following reasons:
1. OS X Developer tools now come with an iSync Plugin builder. Very nice...if you have the time to build it and test it out.
2. Many newer phones are derivatives of currently existing phones. With some google-searching and some work with the plist editor, you can modify a plugin to support your phone. Doesn't always work, and...it takes time to build and test it out.
3. Many other companies sell a single iSync plugin for $3 or $4. But...no updates, and no ability to transfer the license to another computer. You might have your phone for 2 years...but what about your computer? This company allows you to move your license.

Now, these guys allow me to move my license from each computer, and they actually provide free updates to the plugin. More importantly, these guys are FAST with updates. At the time of writing this, Nova Media is the ONLY company providing a working plugin for the Nokia 6650. I tried to modify one from the N78, but the contacts database didn't work. Also, they actually respond to emails.

It's a good product. Granted, I wish iSync would just WORK with SyncML so that we didn't have to search or wait for a phone plugin whenever we get a new model, but at least Nova Media makes it quick and painless for a decent price.
