I sampled roughly 8-10 plug-ins...twice. Trying to find the most flexible yet usable testimonial rotator. In the end, this one was my first choice.
I liked that the styling of the rotator is usable from the get go. It is simple enough to just put on a site, but I could adjust the look and feel pretty easily using CSS.
It also runs pretty smoothly. I think it is the way it is loaded using ajax.
The only feature missing (which it looks like NONE of the rotators have) is the ability to rotate multiple testimonies at once..like flashing 3, scrolling up or something. (That was one of my requirements but in the end they seemed ok with just the one flashing).
Thanks for the taking the time to make a good plug-in!
