I mostly bought this lifetime deal because I wanted the page speed and serp tracking. Everything else that it does is just a bonus and should be useful in time.
The serp tracking seems accurate so far and also the page speed function works well. I like that I can set the serp tracking to be automatic done each week and any additional checks I need can be done manually when I m in the dashboard. This means I can use my credits as much or as little as I want or need.
Overall I am very happy with the purchase.
