The PDFs certainly can be downloaded! When you open them in your web browser, you should see an icon in the corner that sort of looks either like a gear or a floppy disk. Clicking that will give you the option to save to your computer.
Writing a review is easy too! You should see a "write a review" button at the bottom of any given product page.
