My opinion and experience is that Renderhub is really satisfying, there are no Testers that anonymously can grab your assets for free judging on them, it stay's in the creators responsibility to release a satisfying product. Once you hit the post button it is published, you can edit, update your product and post with no delay at any time. Avoiding that a Tester needs to pull out the finger out of hes's a** and hope that it will show off after a few day's standing under a dictatorship. Customers can contact you personally and ask for a fix and update that can be done in no matter of time and updated on the product release also for all other customers with no delay caused through testing's.

If your products are crap, it will show on the ranks, customers will avoid your shop, you have to make refunds, you have no future, you gain no fallowers.

If the customers and products are satisfying then you get a boost, you get fallowers and collectors for your releases and make comparable to other brokers better earnings. I was on rotica yes and I was not pleased at all, with the max of 100 buck a month compared to 500 buck - 3k on RH , considering that every broker charges between 50% and 40 % fee " Even RH " making it up to 6k sales. Top notch vendors with a big group of fallowers even boost up over 6k a month. " I am not in that category as Sex would sell better " 

Concluding that for a Creator it sure is a positive aspect on RH, also not getting the feeling to be just a cheap employee of some Broker, getting more self responsibility for the releases, leaving you even the freedom to promote other places you sell your products or your own webstore.
