The ability to test new products in real time has been huge! We've found that it's given us more confidence when launching features or experimenting with different approaches than we would have had otherwise (or at least much sooner).
Also being able to measure results quickly - so you can make decisions faster as well; this makes our team feel like they're doing their job even better by giving them feedback earlier about what works/doesn't work before going too far down any path!! I wish there was some way of filtering out tests where people aren’t using your product properly though because sometimes those are really hard ones :P But other then THAT nothing bad comes up from testing internally either which means everyone benefits :) Great tool overall if anyone needs help getting started w internal AEs /ampersations etc.. It definitely helps get things rolling quicker but also gives clear directions along how best do set something off correctly rather tha just blindly guessing haha.
