Hey @maximer,
Thanks for taking the time to write a review.
I would like to ask you what feature/s you missed in the free version as you get access to pretty much all of them: Performance Test, Caching, Gzip Compression, Asset Optimization (including the advanced mode), and the Advanced Tools. Pro features are the Assets CDN, Uptime, and a couple more.
Looking forward to your feedback regarding the features and also what we could do to improve the plugin that would make you think it’s worth a 5-star rating :).
Cheers,
Erick
