easy to use Rated 4 out of 5 stars
it is - in difference of many other whois-extensions - very simple and small. no useless gfx, no needless adds (until now, or is this only because my installed ad-block? ,-) , no useless blabla.
i like it very much, because it does what it should. fast and easy.
7 stars only, because it has only a contextmenu-entry. no placeable button, which i better like as a context-menu-entry
