I like that it has different options to block ads, such as only certain types of websites or specific pages within those sites (such an iframe).
It also allows you set up rules for when/how often these blocks should be applied so they don't become too annoying! There are some things about deadbolts interface which could use improvement - but overall its great value at this price point compared with other similar services available out there now-a days!! We've been able solve our own issues around Ad Fraud by using their service without having any problems ourselves in terms of blocking Ads from being served through various channels we're advertising via eCPMs etc.. Its very easy once setup correctly & is well managed over time. No major complaints here really just minor tweaks needed maybe? But thats not necessarily anything against them either though since all businesses have little niggles along side us :) So far.
