I use this module since several years on a joomla 1.5 site and I liked it.
Unfortunately it doesn't work anymore this morning when I tried to re-active it...
The solution to write apostrophe in text is to protect it by a backslash in front of it.
It makes \'
it looks to me like the apostrophe, any in the scrolling text, is interpreted as js or somesuch and breaks the module. this module works great otherwise. I'm giving it an average for this as a customer will generally want to use proper punctuation in a ticker, which this doesn't really allow.
Simple no hassle install for a scrolling text, which I used in my 'breadcrumb' section of Milkway template. I did not want anything that took feeds to make the headline. If you want something simple where you add your own text then this is it.
