I have tried a number of free PDF readers for MAC, and unfortunately, none of them have all the features. Currently, I have three PDF readers installed since I need all of them based on the use case. While all of them have issues, the issues with this one are the most tolerable, so this is usually my go to reader. First the pros. This reader provides crystal clear text and smooth scrolling, (quite surprisingly,) the only free reader to have these two features. Of my other two readers, Adobe's scrolling is very jumpy and Foxit makes the texts blurry on the external monitor. The cons are frustrating, because while the cons of other readers are due to bugs, the cons of this one are by design. First, every time I open a new document, it opens a new window, not a new tab. I have to drag that window to a previously opened window to have them tabbed. Second, I have to select "single page continuous" to have smooth scrolling. I found no options to make it the default view. Third, the text search (cmd F) shows the results in a list. I would prefer to see the result highlighted in the regular view, which is common in all the text readers I have seen before. This helps me see the context, which is not possible in an isolated list. I really wish the developers take note and make some changes to the UI so that I can uninstall the other readers.

When I magnify the pdf so that a page is larger than the screen, and scroll down, the next page is not displayed at the beginning of the page but at the bottom. Is a little annoying because I have to scroll up back up again so can't read a document by just hitting SPACE. Please consider altering SPACE or DOWN to start at the begiining of the next page.Excellent job though! Great reader and will become my go-to reader once scrolling is "normal".

Research papers, textbooks, often free or out of print yet inaccessible for long-term study. I couldn't enter a state of flow with other more commercially known PDF readers. But Reader is elegant and effective. It's fullscreen book display is superb. Coupled with a few Accesibility seetings on your Mac, such as Color Invert and Zoom shorcuts, it becomes a powerful tool for serious academics, students and researchers who must spend hours studying through large works. Can't for further updates and bookmarking features in the future!Ca

This PDF reader is nearly perfect. The only issue I had is that I couldn't figure out how to highlight in different colors. As a PhD student, that part is necessary for me to organize my research. I really liked using this, but without that I can't use it for very much. I'll change to 5 stars & start using it again if/once there is an option to do multi-colored highlighting.
