ProductDyno asked to leave a first impression, so here goes.
Modern interface, focused on selling. The technical setup menu is a bit hidden. Still getting to know the layout.
I think it has much possibilities and potential, so it's worth more exploration - in my case setting up a first course.
I received a 'buy-this-now' email promotion for an unrelated product from PromoteLabs, which said I was on their list because I registered for PD. I think it is their mother company. I do not welcome this kind of cross-promoting, so four stars at this point.
