Stunningly good! So good infact, I've even registered here simply to leave feedback for this service and the Joomla module available for it.

I've headlined "To Good To Be True" because it almost seems to be. I've spent pretty much most of tonight TRYING to find an easy way to display product feeds from CJ without having to fork out money, then literally about 20minutes ago, I came across this extension..and its NOW UP AND RUNNING ON MY SITE. OK, so its not importing product feeds (it never claims to), but if your happy with google style, easy to adjust ads that list relevant products to your page, then this is BRILLIANT.

SO fast to get up and running (as long as you already have your CJ & API numbers), instal the Joomla module from the website, select a few colours and the size of the ads, and off you go.
It also appears (so far) to display ads only from your approved affiliates.

Brilliant guys, thanks.
