I like that it provides me with detailed information about my website visitors, which allows us as marketers to make informed decisions for our business! It's also very easy to use (which makes sense since we're not techies).
The only thing I dislike are some of their reports - they tend to be quite large in size so sometimes you have trouble finding what exactly your looking at when viewing them side by side. But overall this has been great tool for tracking data from websites across multiple channels including organic search and social media marketing campaigns. We've found that using chekelaos gives us more accurate results than other analytics platforms out there such as Google Analytics or even Hubspot because these tools often don't give all the details we need to know how people interact with specific pages within one site.
