I bought this because it was the best of its kind that supported using instapaper with spritz reader technology. Its pretty good overall but lacking in some areas including the layout of the articles and the somewhat confusing and possibly superfluous parts of the UI but if you want to read fast then this is a good value and it works. What is strange is that its not easy to add stuff from other sources or browse to webpages to read. Since I use it via instapaper articles this is not a minor issue currently but would be nice if it could support regular text sources.
