On the face of it, theme looks great - but a different story when you install and activate. Revolution slider is pre-packaged (unlicensed version) and this will NOT activate as a plugin, or update properly. The Orion framework plugin (required) breaks core WP files. The only way you can get around the large raft of issues within this theme is by installing demo content - however this is not going to be advisable if you are using on an existing website with existing content, as it will overwrite everything. Test this theme first before applying. If you don't want the headache of going down code rabbit holes to try and resolve a raft of errors after activation.
