PlusSpec - Is it worth the cost?

Hi, I am debating whether to purchase PlusSpec. They offer 7-day trial, and I am already having issue with activation. They helped me to get activated…but it appears to be unstable platform. It kicks me out in the middle of command and the wall does not work properly. I really liked what their concept of making SU “smart” by making it parametric. I don’t know… I am losing my excitement. Has any of you faced the same sentiment?
