I purchased this extension because I didn't have time to build it myself only to find that the demo doesn't relate to the final product. The extension can only be set in pixel fixed width (not to adjust with a module). It is also not a true accordion, because when you click on a second FAQ, the first stays expanded.
When I asked about this I was told that I could throw more money away ($40) for them to customize the extension. I'm not in the habit of paying a company to develop an extension that I have already paid for.
Much better extensions available. Waste of $25.
