Review on Echobot by David Bar

I like that it provides great detail with regards what you're looking at - but only if your account/profile has been set up correctly (which can be difficult).

Some fields do not have enough options or don't show them until after submitting an initial search query which makes searching more cumbersome because they aren’t always visible when needed. It's easy for me personally since my profile was setup beforehand so everything just flows smoothly once i've entered some basic details about who we want data pulled fro etc..
