Does absolutely everything I required. The only bad part is manually adding the prices one domain at a time, but for a free plugin? who cares!

Hi guys, co.za seems to give error result after search, any advice?

The plugin is undoubtedly a great solution for checking the availability of domains. But it makes me disappointed while I didn't find any option to customize the interface. The default interface is not as same as it's shown. That one is the basic interface. I tried to customize myself with CSS. But I didn't. I don't know what's wrong with this plugin. I'm requested to add the option of interface customization or add documentation of editing the interface properly. Thanks to the devs for developing such a useful plugin.

Deluded. The plugin isn't working properly, not as shown into description and screenshots. It gives just 1 result instead of a list. Happy to modify the rating if improved. 1 star

Plugin works well, I had no problems with .co.uk domains like one reviewer suggests. Unfortunately wasn't compatible with tech, online, site or art which I wanted but can live without for now but definitely 5 star with these. Many thanks! 🙂
