Very solid & nice image optimizing plugin !

used for the first time 1-2 years ago when it was still pretty new, features were more limited then but support was very responsive & friendly answering questions and offering resolutions. revisited the plugin now and see it has been improved, previously purchased credits are still in effect, and it’s a snap to review my account & set it up on additional sites using the API key. love the statistics! overall: crisp and informative interface, easy to use, very configurable, generous free credits & very affordable plans. very impressed & happy!
