Same. It's surprisingly good as a labour saving device. It produces code that I would accept without reservations from a coworker. I still read every line and make tweaks, but they're the same tweaks I would ask for in a code review.

I don't measure my productivity, but I see it in the sort of tasks I tackle after years of waiting. It's especially good at tedious tasks like turning 100 markdown files into 5 json files and updating the code that reads them, for example.
