I like that we have great customer support, they are always willing to help us out whenever needed! There is not much i dislike about reseller engine as it has been good so far for our business needs. The only thing which could be improved in this software would be if you can create your own templates or themes using css/html files instead having them provided by third-party developers who charge quite high fees sometimes. We use resellengine because its an easy way for customers to buy products from other companies without going through multiple middlemen such as agents etc..
