The simplicity, ease-of use makes it one of my favorite networks for affiliates out there! It's pretty much plug & play which I love because you can get started very quickly with minimal effort required by your end users (the customers). There are some minor issues here or there in terms of UI but nothing major as well. We have been using iRefer since our launch date last year now and we haven't seen any negative impact yet. As an independent sales rep who sells into local businesses across various industries, this has helped me close more deals than ever before through referrals.
