It's essentially a toy. If you want an actual training tool, the cheapest options are a used PT, or the competitive cyclist deal.
You have a good point. But consider the fact that even the cheapest unit allows you to do FTP tests and display the data. At the very least, you could see if you are improving or not by keeping track of your progress that way. Then you can upgrade to the full version if you think you need to store and analyze the data.
