Having used it quite a lot I'm not sure it does save me $10 of time per month. At least as often that it generates usefully correct code it generates correct appearing but actually totally wrong code that I have to carefully check and/or debug.
It's quite nice not to have to type generic boilerplate in sometimes I guess but it's very frustrating when it generates junk.
Same experience for me. Checking the code it generated, and the subtle bugs it created which I missed until tests failed, made it at best a net-zero for me. I disabled it after trying for 2 months.
You lasted long than I did! Disabled after a few days.
I think it really depends on what languages you use though. If you use something like Kotlin where there's really almost no boilerplate and the type system is usefully strong, the symbolic logic auto-completion is just far more reliable and helpful. If you're stuck in a language where there's no types, and there's lots of boilerplate to write, then I can see it may be more helpful.
