I have absolutely seen Copilot generate valid C# code with a nasty logic bug. You really need to carefully review every line, and at that point I would usually rather just write it myself. I'm sure there are good use cases, but I just haven't seen anything life-changing in my experiments with various LLM products. The only thing I use day to day is IntelliCode, which saves a bit of typing here and there.
