I've purchased multiple plugins from Code Revolution, and all have exceeded my expectations. They are feature-rich and robust, with lots of customizations, settings and tweaks that you can make.

But their customer service is really top-notch. Code Revolution regularly update their plugins with new features that make my purchases from them more valuable as they age, which is really nice. They also help out in a pinch, with so many ways to tweak and customize there can be a steep learning curve for some of their tools, but they help out in a pinch with reasonable solutions that get the job done.

They also have a comprehensive YouTube channel with lots of tutorials. I highly recommend CR!
