Does Plural Eyes really work and do a good job?

Due to how things are and my limited options I have to manual sync the audio delivered via cd which I get from the houses master mix with my A1s footage. On average that means 10-15 segments/ major clips on most weeks which is tedious and time absorbing.

Does this reliably work on CS 5.5 or CS3.2?

On the surface it sounds great, however I've read online that there may be serious compatibility issues with CS 5.5 and that it doesn't work as well or smoothly with Premiere Pro when compare to other NLE's.

Please, what has been your experience and thoughts in regards to this aid?

I don't want to waste money if this plug-in only is partially effective.

Thanks so much.
