Works, and very simple!
I can see why some rated it one star. There is no WPS Reader window that opens. Just use the menu at the top left. WPS Reader-> File->Open->Choose File->…then the window opens with the file in it. Export to PDF at the top right, done. Took me a couple minutes to figure it out, but once you do, it couldn’t be easier. At $1.99 this weekend it’s a steal!
