I like that this is very user-friendly software for tracking my website performance over time in realtime! This has helped me to improve many areas where our site was performing poorly compared with other sites we are using as benchmarks (and it's helping us keep up!).
The fact you get notified via email when things go wrong helps too - which sometimes takes some getting used to at first but quickly becomes second nature once set right :) Definitely recommend purchasing if your looking into web analytics or even just general statistics about websites/applications running across different platforms & OSes etc., There really isn't anything i dislike specifically from PAMonitor so far!! So overall great product / service all round :). Tracking issues related directly back down onto an end users device would be helpful though maybe add more customisation options suchas allowing multiple IP addresses per account? Perhaps have separate accounts within single computer rather than having 2 seperate computers.
