Pretty good.

Dunno why they felt the need to call it deep, but its a whois program. Ive had no issues with it. The UI is intuitive and, at least to me, aesthetically pleasing.

It saves searches youve done on sites, refreshes when asked, and allows them to be grouped.

If you expect something other than whois, good luck with that, but I didnt, so five stars it is.
