These tools were designed for developers and administrators. Most of the tools have been in use for several years and are very reliable (Inspector and Spex are over 3 years old, the Analyzer is just over a year old, and the GhostHunter is baby at only 4 months old!). However, it's important to note that tools are very powerful and, therefore, any option to change or otherwise delete data is an opportunity to permanently lose data. Have fun, but be sure to wear your selt belt. :)
