It's free! I like how easy it was to get started using this software (just download). The documentation could be improved by adding more tutorials or better instructions overall. A few of my friends did not know what they wanted to do when getting started so there were some people who had issues learning about their program at first but once we got over our initial bumps everything went smoothly. There isn't much else really since all programs have minor things here and there which are probably fine if your looking into creating different kinds of projects. We used torquemdge mainly as a way to make models out of pictures from google images/websites.
