Just no
Another freemium plugin that's not even do what it's advertise.Stopped after about 30% of regeneration process, told me to rate the plugin and did not even allowed me to regenerate missing sizes - i need to regenerate all of them.Most of the features are blocked under paywall.That's not the proper way of introducing your product.

Good plugin, terrible marketing!
Before you can use the plugin, you are FORCED to agree to send technical data to the developer, which is against WordPress terms! They do this by forcing you to agree to check a box saying that you have read the Privacy Policy, which I don't mind, AND agree to sending technical data to the developer, because both are included on the same check box, and if you don't check the box, the plugin won't work! The stupid thing is that the plugin itself works okay, so if it weren't for this coercion, and then nagging me to leave a rating for the plugin, I would have been more than happy to check out the Pro version, instead they have lost a potential customer AND got a 1-star review from me.

Easy to use; great UI
The plugin author(s) must have put a lot of effort into the user interface; it's beautiful! They have made a product that works nicely and is a pleasure to use.
