Just downloaded it and tried it out.

1. You can go to their site at nevercenter.com and download a 30 day trial. I would recommend that if you are unsure.
2. The product was great. I mean really great. Lots of good features and very very intuitive and FAST.
3. You can process a whole folder of photos quickly with this tool. You can apply filters, effects, and adjust the photo (sat, contract, colour etc) all without altering the saved image. When you do save it allows you to change the file name so the original is unaffected. In fact, if you wish you can apply specific effects to ALL photos in a folder with the bulk option.

I agree with number 2! You can also download different filters at nevercenter.com for free.

Lots of fun.
