The quality of the platform is great. Nice design and easy for the users to set up.
Support have also been very helpful and normally helps out within 24 hours. They also did this before I bought the Pro version. WC Vendors are claiming that their support is best, but I prefer dokan support by far. Simple and professional, solving problems.
I use Dokan with theme from WPsoul (about $50), and it works great. They also have amazing(!) support.
Since you can try most of the functions for free you can’t go wrong!
