I like that it's so simple to use; no fancy features or options for advanced users (which is good because my team doesn't need them). It has saved us time in finding vulnerabilities quickly after they're discovered by our security teams! There really isn't anything too bad about this product as far as functionality goes - but if there were any improvements we'd love some more user friendly icons/graphics when viewing information from other devices such as mobile phones etc which could be added into future versions without having to pay additional fees. We've been able find vulnerable websites fairly easily using covil since its introduction at work last year.
