Does anyone use these? Perfect Layers

Ok, so I am going to throw a question out there......does anyone use the Perfect Layers tool.  I find myself very intrigued by this tool.  Drawn to what seems to be faultless edges perfectly straight, seems too tempting.  I am just curious if you have it or have used it what your thoughts are??? Please post if you have used this intriguing tool so that I might get some other opinions....I think this is going to have to go on my must have list.
Here is the link to the video if you haven't seen what I am talking about:
