Have to roll out the plugin on a live site, but pretty happy with the functionalities and performance shown in a staging environment.
From several membership plugin options I had to try over time, ProfilePress has the best price-performance ratio. What I like most are the well considered functionalities that are provided in the package. Where other membership plugins require a number of addons or further plugins to work properly (e.g. SSO, invoicing, etc.), ProfilePress simply has that all included. Fully functional out of the box.
Would have saved me a lot of trouble to have found ProfilePress earlier.

Yes, this is 'just another 5* review'... But there is nothing else than positive feedback I can provide. Happy with that purchase and very positive about future prospectives for the plugin.
