I like how simple it was to install, configure etc. Also liked that all features are free (like adding new modules) with no limits or limitations. The fact there's not much documentation for this product can be considered as one of its downside but still nothing bad about it. If you're looking into something very light-weight CMS then CITUS could fit your needs perfectly well in terms of ease of use / customization options available at zero cost compared to other solutions out here. We used cituscms mainly because we were required by our clients who have their own website hosted elsewhere to give them some flexibility so they do not need to maintain anything themselves anymore when needed.
