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! 🙂

This plugin does exactly what it says on the tin! Domain Name checking is a fairly specialist requirement in any website so i believe this is reflected in the low plugin rating. Let me say i have sent 2 support questions to the developer and both questions have not only resulted in clear responses but instant plugin updates! How many other WP devs respond that quick! Excellent. I wrote a domain name checker many years ago in plain vanilla PHP it was a lot easier when there were only a few dozen TLDs' - this plugin caters for hundreds - so ive no idea what the 1 Star rater is talking about -this plugin caters for all popular and many of the more obscure newer TLDs. Keep up the good work - thanks you.

The free Version can't even handle co.uk or com.au TDLs because of an issue with replacing special characters. Not advisable to install as it will only frustrate and cost a lot of time in which one can basically figure out how to write the whole plug-in your self from scratch.
