I've been using this on my hybrid PVP server for about 10 months, along side Raidable Bases to provide a more pleasant raiding experience overall. It has been actively maintained over this time, and the developer has been responsive and willing to look into issues.

On the admin side this plugin is highly configurable, catering to a wide variety of use cases. You can fine-tune who, what, when, why, and how bases are protected - including things like whether to protect twig construction, vehicles, specific prefabs, etc., how to handle teaming, how to notify players that a base is protected, etc.

On the player side, it seems intuitive/straightforward enough that my players adjusted to it immediately.

It works as expected, and have a great configuration file. Nothing to complain, nothing more to expect. Excellent work, and it is free, what else you want? 

I have been using this plugin for a few weeks.  It needs to be restarted once in a while, but overall, it is the best plugin for offline raid protection that I've used - including paid plugins.  It has multiple options for real time of day and in-game time of day. It allows blacklisting and whitelisting of specific entities, easy to configure, and a decent amount of other options. Developer is quick to resolve issues - which is much faster than some of the paid plugins that cost $20+.  Great plugin and awesome developer - especially for a plugin that is free. Great job!
