Don't buy this theme if you expect a well-maintained theme. It has usability issues, and the developers refuse to fix them. Product filters don’t scroll properly, forcing users to scroll through all products before they can scroll the filters. When I reported it, support admitted the issue but said fixing it required paid custom development. They basically expect merchants to fund their bug fixes.
