After trying several plugins I came across this one. This plugin appears to work great so far. The best part, the developer of this plugin is awesome. He responded quickly to my emails and helped me to solve my problem. A plugin isn't much without a great support team. I Highly recommend this price by user role plugin over the others that are carried here at the Envato Market.
Absolutely brilliant, plugin works very well saving me a whole lot of time, minor little bug reported it and they fixed it straight away and are updating the source. I don't think you could ask for more. 100% recommended.
