I've been using it for the past hour or so.

I told it to make a TODO list (based on my instructions) and now I'm just repeatedly creating a new chat just saying 'work on the todo list'. The thing I'm giving it to do is pretty easy (fix some React components to add types and replace hardcoded strings with props). Doing the same thing in Cursor was annoying, due to the chatter, and the fact I had to click 'Accept all'.

For single file changes, it's nice. I haven't tried it with more complex things yet.
