Even though Christmas is over, you may still want to download Wired Magazine’s TEST reviews publication. It has reviews of all sorts of products and gadgets. If it plugs into something, there’s likely a review contained in its 117 pages.  Download from here. When you get to the site, I suggest you right click on the download link and select "Save target as.." to save it to your computer as opposed to just opening it.
