It does exactly what it should do and is far more better then the standard Joomla module.
Don't understand the critical review below. I had no trouble at all installing and configuring this extension. It works right out of the box. Just take the time to review the settings and create your banners! Great job, wel done.
Works as advertised. Take the time to read the earlier comments en tips to shape it to your liking. Support is quick and to the point. My problem concerning IE7 was resolved with one email. I very much like the look of this tooltip-plugin wich fits my site nicely.
