I wanted this product to work. I installed it three times and uninstalled it all three times. I got disgusted with not only the errors in its "advice", but in the aggravation it caused me by putting corrections right on top of the error nd refusing to move the balloons until I addressed the issue, I couldn't address the issue because the balloon covered it. I couldn't even see it to determine if I needed to correct something, much less to fix it if I found it was an error. The main thing it did for me was to point out typos. While that's a good thing, it's not what was promised. If your main problem is typos, go for it. Otherwise, just use a dictionary.
