All you need is FullStory.

I will skip this question as I was not involved in the implementation.

FullStory support is truly exceptional. They are all friendly and incredibly informed. We have asked them for help on questions our own team could not figure out, and they were either able to solve the problem or set us up with enough information to be able to eventually figure it out on our own. Sometimes, it required some development work to capture additional insights they were not able to set up, but in the end, FullStory Support has directly answered all of our questions or helped us solve our problems 100% of the time. My favorite thing is that they always follow up no matter what to make sure we have what we need. They keep us informed throughout the whole process, and I really appreciate all of their talents!

Personally, I don't have a scenario where I think FullStory is less appropriate. For my day-to-day, it is the tool I use the most, by far. If there is ever a question of how many people do x, I can ascertain that information within 10 minutes usually, with a lot of different ways to visualize the data and group based on various categories (like elite status member, age, etc.). Dev Tools is a powerful way for my team to detect browser-specific / user-specific errors that we can then use to try to recreate the problem. Tech teams and product teams alike really rely on that particular functionality for troubleshooting. For figuring out drop-off points, Funnels and Conversions are invaluable. Both really specifically illustrate where in the journey our customers struggle or succeed! Dashboards is probably the most powerful product in the FullStory package since it combines almost every other product into one super detailed view where you can learn practically anything in one place--all you have to do is set it up! The only downside is that data export is not always in the exact formatting I need or would like, but that is actively being worked on by the team.
