The theme is well-coded with documentation. However, as it no longer supported the slider plugin is outdated and cant load Vimeo videos. You will have to update that and for installation, if you are getting the critical error message make sure you have first installed all the plugins the theme uses. Go to plugins section and it will tell you the recommended ones to install do so and activate.
Everything is great! The theme is bundled with a ton of extras. It's updated whenever the extras update. The authors are on the ball there, so the theme is not neglected like some others I've purchased here on TF.
The theme itself is very easy to use and style, so it's easy to get it looking beautiful really quickly. The code is responsive, so it looks right on other screens as well.
And, the support is top-notch. So yeah, well worth the money.
This theme is fantastic and on top of a great design it has really high quality plugins and flexibility. The support with this theme is also fantastic and they are very responsive to any issues you may have with installation or otherwise - would highly recommend it!
