Not only does Jupiter X offers plenty of pre-made templates – Jupiter X is also really easy to use when you first get a hang of it (I recommend playing around a little before actually changing anything, just to get to know the theme first and how to navigate it). In this context, Artbees offers great tutorials, both as videos and articles.
More importantly, the support from Artbees is beyond amazing: they answer fast and help you with any type of problem, always friendly and helpful. I built my website in no time because Artbees kept answered all of my (foolish and annoying) questions within a few hours (although they say 24 hours, they mostly answer within 1-3 hours). It made me buy their theme once again to give one of my other websites a brush-up. I have tried several different themes from Themeforest and none can live up to the quality and support of Jupiter X from Artbees.
