Flash Optimiser

I am pondering getting Flash Optimiser, an application for reducing swf file size.
Can anyone advise me on how effective/ useful this program is?

Yeah I've used it, it's only useful if you do LOTS of vector animation (like an entire cartoon), if your just trying to optimize a website it isn't that helpful.. actually maybe your talking about a different product, I used Optimaze.

Thanks for replying. Cheers.
