OK, but not slick.
This webpart is fully automated, easy to set up and delivers all the functionality you require from a banner webpart.
However, the fundamental problem I have with this is that the transitions OOB are poor. No transitions are applied to the following image in the queue, so it just blinks into appearance, ruining the fluidity of the previous effect. It's a small thing to fix, but a support call to fix this was refused, on the grounds that
"having them [transitions] work another way would bring issues and compromise user customization options to the web part."
