I was looking for the perfect theme to match the dark grey/blue aesthetic of my old RP forum for Xenforo. Abyss was perfect, plus, it came with TH Nodes and UI.X framework which turned out to be absolutely perfect as I was considering it as a purchase so this was an added bonus. The theme installed perfectly and the amount of customization is amazing. I'm still not entirely through all of the different settings. Very nice theme and very happy with the purchase.
Very glad to hear that you are enjoying Abyss and that it matched your old colors as well! Let us know if you have any issues or questions :)
Well worth the money given the frequent updates and bug fixes. Very easy to customize and modify. Bonus points to ThemeHouse who have been helpful even when I had really dumb issues or questions. My only very minor complaint is that the JS and CSS could some optimization.
Glad to hear that you are enjoying the theme and that our team was able to help you with your support questions! Let us know if we can help with anything else ;)
This is hands down the best theme for XenForo, in my opinion. And I have been here since the early beginning of this software and have tested several products over the years. If you buy a ThemeHouse-product, you will not be disappointed!
Much appreciate the continued support for our themes and your kind review! Continue enjoying Abyss and let us know if we can help with anything else! :)
Nice theme. It's incredibly customizable. Fits 95% of my needs. Abyss comes with a free one year copy for the [TH] Nodes addon and free branding removal - that's awesome for its own. Could use it's own documentation instead of the documentation for UI.X. Keep the good work up!
Thank you so much for the kind review Taminoful as we are glad to hear that you are enjoying Abyss! We will look into the documentation suggestion as well, thanks for that! Please let us know if you have any further questions or concerns! :)
