Has worked well for years!

We have used this on our multilingual sites for years. We did upgrade it to the paid version after only a few months of use. For a small price, it was worth it for users to be able to download the PDFs right from the toolbar in the displayed PDF. We only had one instance (after a plugin update) where we had a minor issue with the scrollbars showing up (when they had been turned off). The PDF Embedder support was quite responsive, and they fixed this issue in the very next release.
