I like how easy it was setup with our team members who were not familiar at all in regards setting up cookie opt outs from their website or apps we are working within! It's great because you can set multiple domains which makes managing them easier than having one domain per product where each would have its own unique settings (which could be confusing).
The only thing i dislike about using Cookie Opt Out Toolkit as opposed to other tools available online such us https://www.bkftechcenter.com/, but maybe more so now after recent updates they made recently - there seems less customization options compared when before update if didn't know what exactly your looking for then chances may arise finding something else better suited instead? We use Cookies Toptool kit primarily through Chrome browser however also via Firefox & Safari browsers too just incase some users don�.
