The ability to have a single pane of glass for all of our data is great. We can use Tonic to make sure that our QA has the same test data we use in the field! The support is great. The team is constantly improving the product and adding new features. The only thing I don't like is the price. We pay a fee per month for our QA to use Tonic. I know this is very costly, but this is all I've heard from other companies. I hope it's just me. We also use Tonic to monitor our user flows. We also use this to monitor our performance.
